The lines y = 11x + 14 and y = 91 meet at x = 7. 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+14=9111x + 14 = 91
  2. 2

    Subtract 14 from both sides:

    11x+14−14=91−14 ⇒ 11x=7711x + 14 - 14 = 91 - 14 \ \Rightarrow\ 11x = 77
  3. 3

    Divide both sides by 11:

    11x11=7711 ⇒ x=7\frac{11x}{11} = \frac{77}{11} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
