What does the Algebra section test on the Digital SAT? The correct answer is your ability to work with linear equations, linear inequalities, and systems of equations. This section also tests your ability to translate real-world scenarios into algebraic models. Algebra is one of the four content domains in the Digital SAT Math section, and it typically makes up a significant portion of the scored questions, so building fluency here has a direct impact on your overall Math score.

If you're planning to join SAT classes in Dubai, practicing algebra questions regularly can help you strengthen these core skills and approach the math section with greater confidence. The Digital SAT Algebra domain assesses your ability to solve linear equations in one variable, interpret and solve linear equations and inequalities in two variables, work with systems of two linear equations, and understand linear functions. The practice questions below are designed to help you master these skills and become more comfortable with the Digital SAT exam format:

  1. Question on Linear Equations in One Variable

Solve for x.

3x + 7 = 22

  1. 3 
  2. 5 
  3. 7 
  4. 15

Answer: B - 5

Explanation: Subtracting 7 from both sides gives 3x = 15, and dividing both sides by 3 gives x = 5.

  1. Question on Linear Equations in One Variable 

Solve for x.

2(x - 4) = 3x - 10

  1. -2 
  2. 2 
  3. 6 
  4. -6

Answer: B - 2

Explanation: Distributing gives 2x - 8 = 3x - 10. Subtracting 2x from both sides gives -8 = x - 10, so x = 2.

  1. Question on Linear Equations in Two Variables 

Which of the following is a solution to the equation below?

2x + y = 10

  1. (2, 5) 
  2. (3, 4) 
  3. (4, 2) 
  4. (5, 1)

Answer: C - (4, 2)

Explanation: Substituting x = 4 and y = 2 gives 2(4) + 2 = 10, which satisfies the equation.

  1. Question on Linear Inequalities in One Variable 

Which value of x satisfies the inequality below?

4x - 3 > 9

  1. 2 B. 3 C. 4 D. 1

Answer: C - 4

Explanation: Adding 3 to both sides gives 4x > 12, so x > 3. Of the choices, only 4 is greater than 3.

  1. Question on Linear Inequalities in Two Variables 

Read the scenario.

A parking garage charges a flat fee of $5 plus $2 per hour. Which inequality represents the hours a driver can park if they want to spend no more than $17?

  1. 5 + 2h ≤ 17 
  2. 5 + 2h ≥ 17 
  3. 2 + 5h ≤ 17 
  4. 5h + 2 ≥ 17

Answer: A - 5 + 2h ≤ 17

Explanation: The total cost is the flat fee plus the hourly charge, and "no more than" translates to "less than or equal to."

  1. Question on Systems of Two Linear Equations 

Solve the system of equations.

x + y = 12 x - y = 4

  1. x = 8, y = 4 
  2. x = 4, y = 8 
  3. x = 6, y = 6 
  4. x = 10, y = 2

Answer: A - x = 8, y = 4

Explanation: Adding the two equations eliminates y, giving 2x = 16, so x = 8. Substituting back gives y = 4.

  1. Question on Systems of Two Linear Equations 

A system of two linear equations is graphed, and the two lines are parallel. How many solutions does the system have?

  1. Exactly one 
  2. Exactly two 
  3. No solutions 
  4. Infinitely many solutions

Answer: C - No solutions

Explanation: Parallel lines never intersect, so there is no point that satisfies both equations at once.

  1. Question on Systems of Two Linear Equations 

Read the scenario.

A theater sells adult tickets for $12 and child tickets for $8. One evening, the theater sold 150 tickets for a total of $1,560. Which system of equations represents this situation, where a is the number of adult tickets and c is the number of child tickets?

  1. a + c = 150 and 12a + 8c = 1,560 
  2. a + c = 1,560 and 12a + 8c = 150 
  3. a - c = 150 and 8a + 12c = 1,560 
  4. a + c = 150 and 8a + 12c = 1,560

Answer: A - a + c = 150 and 12a + 8c = 1,560

Explanation: The total number of tickets sold is 150, and the total revenue is the sum of each ticket type multiplied by its price.

  1. Question on Linear Functions 

A linear function f is defined by f(x) = 4x - 9. What is the value of f(3)?

  1. -3 
  2. 3 
  3. 12 
  4. 21

Answer: B - 3

Explanation: Substituting x = 3 gives f(3) = 4(3) - 9 = 12 - 9 = 3.

  1. Question on Linear Functions

The graph of a linear function passes through the points (0, 5) and (2, 9). What is the slope of the function?

  1. 1 
  2. 2 
  3. 4 
  4. 5

Answer: B - 2

Explanation: Slope is the change in y divided by the change in x, so (9 - 5) / (2 - 0) = 4/2 = 2.

  1. Question on Interpreting Linear Models

 A company's monthly profit, in dollars, is modeled by the equation P = 45n - 900, where n is the number of units sold. What does the number 900 represent in this context?

  1. The profit earned per unit sold. 
  2. The total number of units sold in a month. 
  3. The company's fixed monthly costs. 
  4. The maximum possible monthly profit.

Answer: C - The company's fixed monthly costs.

Explanation: The 900 is subtracted regardless of how many units are sold, meaning it represents a fixed cost that must be covered before the company turns a profit.

  1. Question on Linear Equations in One Variable 

Solve for x.

(x + 5) / 3 = 4

  1. 3 B. 7 C. 9 D. 12

Answer: B - 7

Explanation: Multiplying both sides by 3 gives x + 5 = 12, so x = 7.

  1. Question on Systems of Two Linear Equations

For which value of k does the system below have no solution?

y = 3x + 4, y = kx + 7

  1. 1 
  2. 2 
  3. 3 
  4. 4

Answer: C - 3

Explanation: A system of two linear equations has no solution when the lines are parallel, meaning they have the same slope but different y-intercepts. Since the slopes are already equal when k = 3, and the y-intercepts (4 and 7) differ, the system has no solution.

  1. Question on Linear Inequalities in Two Variables 

Read the scenario.

A student has already read 40 pages of a book and plans to read 15 pages per day, d. Which inequality represents the number of days needed for the student to have read at least 130 pages in total?

  1. 40 + 15d ≥ 130 
  2. 40 + 15d ≤ 130 
  3. 15 + 40d ≥ 130 
  4. 40d + 15 ≥ 130

Answer: A - 40 + 15d ≥ 130

Explanation: The total pages read are the pages already completed plus the daily rate multiplied by the number of days, and "at least" translates to "greater than or equal to."

  1. Question on Linear Functions

The table below shows values of a linear function g

x

g(x)

1

7

3

15

5

23

What is the equation of g(x)?

  1. g(x) = 2x + 5 
  2. g(x) = 4x + 3 
  3. g(x) = 4x + 5 
  4. g(x) = 3x + 4

Answer: B - g(x) = 4x + 3

Explanation: The slope is (15 - 7) / (3 - 1) = 4. Using the point (1, 7), we have 7 = 4(1) + b, which gives b = 3, so g(x) = 4x + 3.
