The lines y = 8x + 8 and y = 160 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.

    8x+8=1608x + 8 = 160
  2. 2

    Subtract 8 from both sides:

    8x+8−8=160−8 ⇒ 8x=1528x + 8 - 8 = 160 - 8 \ \Rightarrow\ 8x = 152
  3. 3

    Divide both sides by 8:

    8x8=1528 ⇒ x=19\frac{8x}{8} = \frac{152}{8} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
