The lines y = 11x + 8 and y = 151 meet at x = 13. 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.

    11x+8=15111x + 8 = 151
  2. 2

    Subtract 8 from both sides:

    11x+8−8=151−8 ⇒ 11x=14311x + 8 - 8 = 151 - 8 \ \Rightarrow\ 11x = 143
  3. 3

    Divide both sides by 11:

    11x11=14311 ⇒ x=13\frac{11x}{11} = \frac{143}{11} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
