Solve each equation. Show every step and check your answer by substituting it back in.
1.x + 19 = 23
Answer: x = 4
- Subtract 19 from both sides
- x = 23 − 19 = 4
2.4x = 28
Answer: x = 7
- Divide both sides by 4
- x = 28 ÷ 4 = 7
3.x − 20 = −17
Answer: x = 3
- Add 20 to both sides
- x = −17 + 20 = 3
4.x − 4 = 2
Answer: x = 6
- Add 4 to both sides
- x = 2 + 4 = 6
5.x − 8 = −4
Answer: x = 4
- Add 8 to both sides
- x = −4 + 8 = 4
6.x − 5 = 2
Answer: x = 7
- Add 5 to both sides
- x = 2 + 5 = 7
7.9x = 9
Answer: x = 1
- Divide both sides by 9
- x = 9 ÷ 9 = 1
8.4x = 12
Answer: x = 3
- Divide both sides by 4
- x = 12 ÷ 4 = 3
9.5x = 60
Answer: x = 12
- Divide both sides by 5
- x = 60 ÷ 5 = 12
10.5x = 45
Answer: x = 9
- Divide both sides by 5
- x = 45 ÷ 5 = 9
11.9x = 54
Answer: x = 6
- Divide both sides by 9
- x = 54 ÷ 9 = 6
12.x + 13 = 17
Answer: x = 4
- Subtract 13 from both sides
- x = 17 − 13 = 4
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.
