Show answers and working
  1. 1. x = 8

    Subtract 6 from both sides: x = 8. Check: 1 × 8 + 6 = 14.

  2. 2. x = 0

    Subtract 19 from both sides: x = 0. Check: 1 × 0 + 19 = 19.

  3. 3. x = 9

    Subtract 2 from both sides: x = 9. Check: 1 × 9 + 2 = 11.

  4. 4. x = 9

    Subtract 4 from both sides: x = 9. Check: 1 × 9 + 4 = 13.

  5. 5. x = 2

    Subtract 7 from both sides: 4x = 8. Divide by 4: x = 2. Check: 4 × 2 + 7 = 15.

  6. 6. x = 6

    Subtract 19 from both sides: 7x = 42. Divide by 7: x = 6. Check: 7 × 6 + 19 = 61.

  7. 7. x = -3

    Subtract 6 from both sides: 6x = -18. Divide by 6: x = -3. Check: 6 × -3 + 6 = -12.

  8. 8. x = -3

    Subtract 17 from both sides: 2x = -6. Divide by 2: x = -3. Check: 2 × -3 + 17 = 11.

  9. 9. x = 10

    Subtract 1x from both sides: 1x + 6 = 16. Subtract 6: 1x = 10. Divide by 1: x = 10.

  10. 10. x = -10

    Subtract 2x from both sides: 5x + 3 = -47. Subtract 3: 5x = -50. Divide by 5: x = -10.

  11. 11. x = -3

    Subtract 1x from both sides: 5x + 17 = 2. Subtract 17: 5x = -15. Divide by 5: x = -3.

  12. 12. x = -2

    Subtract 1x from both sides: 2x + 14 = 10. Subtract 14: 2x = -4. Divide by 2: x = -2.

Worked examples

Easy example

Solve x + 12 = 21.

  1. Subtract 12 from both sides: x = 9.
  2. Check: 1 × 9 + 12 = 21.
  3. Answer: x = 9
Medium example

Solve 4x + 15 = 35.

  1. Subtract 15 from both sides: 4x = 20.
  2. Divide by 4: x = 5.
  3. Check: 4 × 5 + 15 = 35.
  4. Answer: x = 5
Hard example

Solve 4x + 9 = 3x + 17.

  1. Subtract 3x from both sides: 1x + 9 = 17.
  2. Subtract 9: 1x = 8.
  3. Divide by 1: x = 8.
  4. 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 −.

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.
