The lines y = 2x + 15 and y = 53 meet at x = 19. 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+15=532x + 15 = 53
  2. 2

    Subtract 15 from both sides:

    2x+15−15=53−15 ⇒ 2x=382x + 15 - 15 = 53 - 15 \ \Rightarrow\ 2x = 38
  3. 3

    Divide both sides by 2:

    2x2=382 ⇒ x=19\frac{2x}{2} = \frac{38}{2} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
