The lines y = 9x + 2 and y = 119 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.

    9x+2=1199x + 2 = 119
  2. 2

    Subtract 2 from both sides:

    9x+2−2=119−2 ⇒ 9x=1179x + 2 - 2 = 119 - 2 \ \Rightarrow\ 9x = 117
  3. 3

    Divide both sides by 9:

    9x9=1179 ⇒ x=13\frac{9x}{9} = \frac{117}{9} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
