Part (a) · 1 mark

Simplify the sum p + p + p + p.

  1. 1p + p + p + p = 4p

Answer4p

Part (b) · 2 marks

Simplify 5e + 6f + 7e − 2f by collecting like terms.

  1. 15e + 7e = 12e
  2. 26f − 2f = 4f
  3. 312e + 4f

Answer12e + 4f

Part (c) · 1 mark

Solve 13 − x = 7 to find x.

  1. 113 − x = 7
  2. 2x = 13 − 7
  3. 3x = 6

Answer6

Part (d) · 2 marks

Solve 4y + 7 = 43 to find y.

  1. 14y + 7 = 43
  2. 24y = 43 − 7
  3. 34y = 36
  4. 4y = 36 ÷ 4
  5. 5y = 9
