  • Solve for x:   5x + 4x - 27 = 81
    x = 12
  • Hannah has $50. She buy 2 cups of bubble tea at $x each and 5 pancakes at $y each. How much does Hannah spend altogether?
    $(2x + 5y)
  • Factorise: −15x + 3z
    −3(5x − z)
  • Solve for x:   xm = np
    x = np/m
  • Solve for w:   g = 1/6(w+40)
    w = 6g - 40
  • Factorise: -121x + 44
    -11(11x-4) OR 11(-11x+4)
  • Factorise -21ax + 56ay
    7a (-3x + 8y) or -7a (3x - 8y)
  • Expand and Simplify -(4x - 9y) - 9y
    -4x
  • Solve for x:    6 = mx + b
    x = 6-b/m
  • Factorise -8ax + 10bx + 12cx completely
    2x (-4a + 5b + 6c)
  • Factorise: 9x - 24z
    3(3x-8z)
  • Solve for a:   19a - 12 - 4a = -57
    a = -3
  • Factorise: 100 − 40y
    20(5 – 2y)
  • Factorise: -3x - 6
    -3(x+2) OR 3(-x-2)
