The lines y = 12x + 6 and y = 222 meet at x = 18. The solution of the equation is the x-coordinate of the point where the two sides are equal.

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+6=22212x + 6 = 222
  2. 2

    Subtract 6 from both sides:

    12x+6−6=222−6 ⇒ 12x=21612x + 6 - 6 = 222 - 6 \ \Rightarrow\ 12x = 216
  3. 3

    Divide both sides by 12:

    12x12=21612 ⇒ x=18\frac{12x}{12} = \frac{216}{12} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
