The lines y = 8x + 15 and y = 127 meet at x = 14. 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+15=1278x + 15 = 127
  2. 2

    Subtract 15 from both sides:

    8x+15−15=127−15 ⇒ 8x=1128x + 15 - 15 = 127 - 15 \ \Rightarrow\ 8x = 112
  3. 3

    Divide both sides by 8:

    8x8=1128 ⇒ x=14\frac{8x}{8} = \frac{112}{8} \ \Rightarrow\ x = 14
  4. 4

    Check: put x = 14 back into the equation.
