How to work it out

  1. 1

    The goal is to get x alone. Undo the operations in the opposite order: first the addition, then the multiplication.

    12x+15=18312x + 15 = 183
  2. 2

    Subtract 15 from both sides:

    12x+15−15=183−15 ⇒ 12x=16812x + 15 - 15 = 183 - 15 \ \Rightarrow\ 12x = 168
  3. 3

    Divide both sides by 12:

    12x12=16812 ⇒ x=14\frac{12x}{12} = \frac{168}{12} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
