TEAS Math: Algebra and Equations 2 — Questions and Answers
Question 1: Solve for x: 3x - 7 = 14.
- 7 (Correct answer)
- 21
- 3
- 9
Correct answer: 7
Add 7 to both sides to get 3x = 21, then divide by 3 to get x = 7.
Question 2: What is the value of y when 2(y + 4) = 18?
- 5 (Correct answer)
- 7
- 11
- 9
Correct answer: 5
Distribute to get 2y + 8 = 18, so 2y = 10 and y = 5.
Question 3: Simplify the expression: 4x + 3x - 2x.
- 5x (Correct answer)
- 9x
- x
- 7x
Correct answer: 5x
Combine like terms: 4 + 3 - 2 = 5, giving 5x.
Question 4: Solve for x: x/5 = 6.
- 30 (Correct answer)
- 11
- 1.2
- 1
Correct answer: 30
Multiply both sides by 5 to get x = 30.
Question 5: If 5x + 2 = 3x + 10, what is x?
- 4 (Correct answer)
- 6
- 2
- 3
Correct answer: 4
Subtract 3x and 2 from both sides to get 2x = 8, so x = 4.
Question 6: Evaluate 2a + 3b when a = 4 and b = 5.
- 23 (Correct answer)
- 20
- 17
- 35
Correct answer: 23
2(4) + 3(5) = 8 + 15 = 23.
Question 7: Solve the inequality: x + 6 < 10.
- x < 4 (Correct answer)
- x > 4
- x < 16
- x > 16
Correct answer: x < 4
Subtract 6 from both sides to get x < 4.
