10 Algebra Questions and Answers

Try to solve these questions one by one, then see the solution. Each question includes a detailed answer, so you not only solve — you understand.

1. Solve: 3x + 5 = 20
Answer:
3x = 20 − 5 = 15
x = 15 ÷ 3 = 5

2. Solve for x: 2(x − 4) = 10
Answer:
2x − 8 = 10
2x = 18
x = 9

3. Simplify: (x + 2)(x − 2)
Answer:
This is a difference of squares:
x² − 4

4. Solve: x² − 4x − 5 = 0
Answer:
Factor: (x − 5)(x + 1) = 0
x = 5 or −1

5. If 5x − 2 = 3x + 6, what is x?
Answer:
2x = 8
x = 4

6. Expand: (2x + 3)(x − 1)
Answer:
= 2x² − 2x + 3x − 3
= 2x² + x − 3

7. Solve: (x/2) + 3 = 7
Answer:
x/2 = 4
x = 8

8. Factor: x² + 7x + 10 Answer:
= (x + 5)(x + 2)

9. Solve for x: 4x − (2x + 3) = 7
Answer:
4x − 2x − 3 = 7
→ 2x = 10
→ x = 5

10. If x² = 49, what is x?
Answer:
x = 7 or −7
