The lines y = 11x + 4 and y = 169 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.

    11x+4=16911x + 4 = 169
  2. 2

    Subtract 4 from both sides:

    11x+4−4=169−4 ⇒ 11x=16511x + 4 - 4 = 169 - 4 \ \Rightarrow\ 11x = 165
  3. 3

    Divide both sides by 11:

    11x11=16511 ⇒ x=15\frac{11x}{11} = \frac{165}{11} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
