Solve each equation. Show every step and check your answer by substituting it back in.
1.5x = 5
Answer: x = 1
- Divide both sides by 5
- x = 5 ÷ 5 = 1
2.x − 10 = −2
Answer: x = 8
- Add 10 to both sides
- x = −2 + 10 = 8
3.3x = 30
Answer: x = 10
- Divide both sides by 3
- x = 30 ÷ 3 = 10
4.9x = 63
Answer: x = 7
- Divide both sides by 9
- x = 63 ÷ 9 = 7
5.x + 7 = 19
Answer: x = 12
- Subtract 7 from both sides
- x = 19 − 7 = 12
6.x − 18 = −12
Answer: x = 6
- Add 18 to both sides
- x = −12 + 18 = 6
7.x − 13 = −9
Answer: x = 4
- Add 13 to both sides
- x = −9 + 13 = 4
8.9x = 108
Answer: x = 12
- Divide both sides by 9
- x = 108 ÷ 9 = 12
9.x + 4 = 16
Answer: x = 12
- Subtract 4 from both sides
- x = 16 − 4 = 12
10.9x = 54
Answer: x = 6
- Divide both sides by 9
- x = 54 ÷ 9 = 6
11.x − 14 = −12
Answer: x = 2
- Add 14 to both sides
- x = −12 + 14 = 2
12.x + 5 = 11
Answer: x = 6
- Subtract 5 from both sides
- x = 11 − 5 = 6
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
