The lines y = 8x + 14 and y = 134 meet at x = 15. 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+14=1348x + 14 = 134
  2. 2

    Subtract 14 from both sides:

    8x+14−14=134−14 ⇒ 8x=1208x + 14 - 14 = 134 - 14 \ \Rightarrow\ 8x = 120
  3. 3

    Divide both sides by 8:

    8x8=1208 ⇒ x=15\frac{8x}{8} = \frac{120}{8} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
