DETAILED RATIONALES GRADED A+
1. Solve for x: 3x - 7 = 14.
A. 5
B. 7
C. 9
D. 11
Correct Answer: B. 7
Rationale: Add 7 to both sides to get 3x = 21. Divide both sides by 3 to get x = 7.
Choices A, C, and D are incorrect based on these algebraic steps.
2. Solve for x: 2(x + 4) = 18.
A. 3
B. 5
C. 7
,D. 9
Correct Answer: B. 5
Rationale: Distribute the 2 to get 2x + 8 = 18. Subtract 8 from both sides to get 2x
= 10, then divide by 2 to get x = 5. Choices A, C, and D are incorrect.
3. Solve for x: (x / 3) + 2 = 5.
A. 6
B. 7
C. 9
D. 12
Correct Answer: C. 9
Rationale: Subtract 2 from both sides to get x / 3 = 3. Multiply both sides by 3 to
get x = 9. Choices A, B, and D are incorrect.
4. Solve for x: 5x - 3 = 2x + 9.
A. 2
,B. 3
C. 4
D. 6
Correct Answer: C. 4
Rationale: Subtract 2x from both sides to get 3x - 3 = 9. Add 3 to both sides to get
3x = 12. Divide by 3 to get x = 4. Choices A, B, and D are incorrect.
5. Solve for x: -2x + 8 = 20.
A. -8
B. -6
C. 6
D. 8
Correct Answer: B. -6
Rationale: Subtract 8 from both sides to get -2x = 12. Divide by -2 to get x = -6.
Choices A, C, and D are incorrect.
6. Solve for x: 4(x - 1) = 2(x + 3).
, A. 3
B. 4
C. 5
D. 6
Correct Answer: C. 5
Rationale: Distribute to get 4x - 4 = 2x + 6. Subtract 2x and add 4 to both sides to
get 2x = 10. Divide by 2 to get x = 5. Choices A, B, and D are incorrect.
7. Solve for x: 3(2x - 1) = 5x + 4.
A. 5
B. 6
C. 7
D. 8
Correct Answer: C. 7
Rationale: Distribute to get 6x - 3 = 5x + 4. Subtract 5x and add 3 to both sides to
get x = 7. Choices A, B, and D are incorrect.
