The lines y = 12x + 9 and y = 201 meet at x = 16. 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+9=20112x + 9 = 201
  2. 2

    Subtract 9 from both sides:

    12x+9−9=201−9 ⇒ 12x=19212x + 9 - 9 = 201 - 9 \ \Rightarrow\ 12x = 192
  3. 3

    Divide both sides by 12:

    12x12=19212 ⇒ x=16\frac{12x}{12} = \frac{192}{12} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
