The lines y = 2x + 12 and y = 52 meet at x = 20. 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.

    2x+12=522x + 12 = 52
  2. 2

    Subtract 12 from both sides:

    2x+12−12=52−12 ⇒ 2x=402x + 12 - 12 = 52 - 12 \ \Rightarrow\ 2x = 40
  3. 3

    Divide both sides by 2:

    2x2=402 ⇒ x=20\frac{2x}{2} = \frac{40}{2} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
