Solve each equation. Show every step and check your answer by substituting it back in.
1.3x = 9
Answer: x = 3
- Divide both sides by 3
- x = 9 ÷ 3 = 3
2.x − 10 = 0
Answer: x = 10
- Add 10 to both sides
- x = 0 + 10 = 10
3.x − 19 = −18
Answer: x = 1
- Add 19 to both sides
- x = −18 + 19 = 1
4.x + 4 = 8
Answer: x = 4
- Subtract 4 from both sides
- x = 8 − 4 = 4
5.x + 9 = 18
Answer: x = 9
- Subtract 9 from both sides
- x = 18 − 9 = 9
6.x + 17 = 28
Answer: x = 11
- Subtract 17 from both sides
- x = 28 − 17 = 11
7.9x = 108
Answer: x = 12
- Divide both sides by 9
- x = 108 ÷ 9 = 12
8.9x = 36
Answer: x = 4
- Divide both sides by 9
- x = 36 ÷ 9 = 4
9.2x = 24
Answer: x = 12
- Divide both sides by 2
- x = 24 ÷ 2 = 12
10.x + 5 = 17
Answer: x = 12
- Subtract 5 from both sides
- x = 17 − 5 = 12
11.x + 8 = 10
Answer: x = 2
- Subtract 8 from both sides
- x = 10 − 8 = 2
12.4x = 20
Answer: x = 5
- Divide both sides by 4
- x = 20 ÷ 4 = 5
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.
