Show answers and working
1. x = 8
Subtract 12 from both sides: x = 8. Check: 1 × 8 + 12 = 20.
2. x = 11
Subtract 3 from both sides: x = 11. Check: 1 × 11 + 3 = 14.
3. x = 2
Subtract 8 from both sides: x = 2. Check: 1 × 2 + 8 = 10.
4. x = 12
Subtract 4 from both sides: x = 12. Check: 1 × 12 + 4 = 16.
5. x = 7
Subtract 14 from both sides: 4x = 28. Divide by 4: x = 7. Check: 4 × 7 + 14 = 42.
6. x = -1
Subtract 11 from both sides: 9x = -9. Divide by 9: x = -1. Check: 9 × -1 + 11 = 2.
7. x = 9
Subtract 10 from both sides: 8x = 72. Divide by 8: x = 9. Check: 8 × 9 + 10 = 82.
8. x = -2
Subtract 8 from both sides: 9x = -18. Divide by 9: x = -2. Check: 9 × -2 + 8 = -10.
9. x = 12
Subtract 1x from both sides: 1x + 20 = 32. Subtract 20: 1x = 12. Divide by 1: x = 12.
10. x = -10
Subtract 1x from both sides: 1x + 10 = 0. Subtract 10: 1x = -10. Divide by 1: x = -10.
11. x = 6
Subtract 5x from both sides: 1x + 1 = 7. Subtract 1: 1x = 6. Divide by 1: x = 6.
12. x = 8
Subtract 1x from both sides: 4x + 13 = 45. Subtract 13: 4x = 32. Divide by 4: x = 8.
Worked examples
Solve x + 20 = 24.
- Subtract 20 from both sides: x = 4.
- Check: 1 × 4 + 20 = 24.
- Answer: x = 4
Solve 8x + 17 = -23.
- Subtract 17 from both sides: 8x = -40.
- Divide by 8: x = -5.
- Check: 8 × -5 + 17 = -23.
- Answer: x = -5
Solve 8x + 14 = 1x + -42.
- Subtract 1x from both sides: 7x + 14 = -42.
- Subtract 14: 7x = -56.
- Divide by 7: x = -8.
- Answer: x = -8

Common mistakes
What learners typically get wrong, and how to fix it.
Does an operation to only one side.
Correction: Keep the balance — both sides, every time.
Uses the wrong inverse (subtracts to undo multiplying).
Correction: Undo × with ÷ and + with −.
