The lines y = 8x + 8 and y = 152 meet at x = 18. 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=1528x + 8 = 152
  2. 2

    Subtract 8 from both sides:

    8x+8−8=152−8 ⇒ 8x=1448x + 8 - 8 = 152 - 8 \ \Rightarrow\ 8x = 144
  3. 3

    Divide both sides by 8:

    8x8=1448 ⇒ x=18\frac{8x}{8} = \frac{144}{8} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
