The lines y = 12x + 11 and y = 107 meet at x = 8. 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+11=10712x + 11 = 107
  2. 2

    Subtract 11 from both sides:

    12x+11−11=107−11 ⇒ 12x=9612x + 11 - 11 = 107 - 11 \ \Rightarrow\ 12x = 96
  3. 3

    Divide both sides by 12:

    12x12=9612 ⇒ x=8\frac{12x}{12} = \frac{96}{12} \ \Rightarrow\ x = 8
  4. 4

    Check: put x = 8 back into the equation.
