Show answers and working
  1. 1. x = 0

    Subtract 11 from both sides: x = 0. Check: 1 × 0 + 11 = 11.

  2. 2. x = 6

    Subtract 4 from both sides: x = 6. Check: 1 × 6 + 4 = 10.

  3. 3. x = 10

    Subtract 8 from both sides: x = 10. Check: 1 × 10 + 8 = 18.

  4. 4. x = 9

    Subtract 1 from both sides: x = 9. Check: 1 × 9 + 1 = 10.

  5. 5. x = -3

    Subtract 17 from both sides: 9x = -27. Divide by 9: x = -3. Check: 9 × -3 + 17 = -10.

  6. 6. x = 12

    Subtract 17 from both sides: 8x = 96. Divide by 8: x = 12. Check: 8 × 12 + 17 = 113.

  7. 7. x = 1

    Subtract 6 from both sides: 7x = 7. Divide by 7: x = 1. Check: 7 × 1 + 6 = 13.

  8. 8. x = 11

    Subtract 2 from both sides: 6x = 66. Divide by 6: x = 11. Check: 6 × 11 + 2 = 68.

  9. 9. x = -2

    Subtract 1x from both sides: 5x + 1 = -9. Subtract 1: 5x = -10. Divide by 5: x = -2.

  10. 10. x = 2

    Subtract 5x from both sides: 1x + 3 = 5. Subtract 3: 1x = 2. Divide by 1: x = 2.

  11. 11. x = 12

    Subtract 3x from both sides: 2x + 3 = 27. Subtract 3: 2x = 24. Divide by 2: x = 12.

  12. 12. x = -4

    Subtract 4x from both sides: 4x + 18 = 2. Subtract 18: 4x = -16. Divide by 4: x = -4.

Worked examples

Easy example

Solve x + 7 = 7.

  1. Subtract 7 from both sides: x = 0.
  2. Check: 1 × 0 + 7 = 7.
  3. Answer: x = 0
Medium example

Solve 6x + 20 = 14.

  1. Subtract 20 from both sides: 6x = -6.
  2. Divide by 6: x = -1.
  3. Check: 6 × -1 + 20 = 14.
  4. Answer: x = -1
Hard example

Solve 6x + 7 = 2x + -17.

  1. Subtract 2x from both sides: 4x + 7 = -17.
  2. Subtract 7: 4x = -24.
  3. Divide by 4: x = -6.
  4. Answer: x = -6

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 −.

Teacher tips

  • · Always ask pupils to substitute their answer back in.

Parent tips

  • · 'I think of a number' puzzles at dinner.

Real-life applications

  • · Working out an unknown price or time from a total.
