Year 8 Solving Linear Equations Worksheet — Level 1 (Set 2) — Answers

Solve each equation. Show every step and check your answer by substituting it back in.

1.x − 10 = 2

Answer: x = 12

  1. Add 10 to both sides
  2. x = 2 + 10 = 12
2.x + 2 = 8

Answer: x = 6

  1. Subtract 2 from both sides
  2. x = 8 − 2 = 6
3.x + 9 = 19

Answer: x = 10

  1. Subtract 9 from both sides
  2. x = 19 − 9 = 10
4.x − 12 = −8

Answer: x = 4

  1. Add 12 to both sides
  2. x = −8 + 12 = 4
5.x + 20 = 28

Answer: x = 8

  1. Subtract 20 from both sides
  2. x = 28 − 20 = 8
6.x − 17 = −16

Answer: x = 1

  1. Add 17 to both sides
  2. x = −16 + 17 = 1
7.7x = 14

Answer: x = 2

  1. Divide both sides by 7
  2. x = 14 ÷ 7 = 2
8.x + 20 = 25

Answer: x = 5

  1. Subtract 20 from both sides
  2. x = 25 − 20 = 5
9.x − 8 = −1

Answer: x = 7

  1. Add 8 to both sides
  2. x = −1 + 8 = 7
10.x + 6 = 15

Answer: x = 9

  1. Subtract 6 from both sides
  2. x = 15 − 6 = 9
11.x − 14 = −4

Answer: x = 10

  1. Add 14 to both sides
  2. x = −4 + 14 = 10
12.x + 17 = 28

Answer: x = 11

  1. Subtract 17 from both sides
  2. x = 28 − 17 = 11
