The lines y = 9x + 13 and y = 157 meet at x = 16. 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+13=1579x + 13 = 157
  2. 2

    Subtract 13 from both sides:

    9x+13−13=157−13 ⇒ 9x=1449x + 13 - 13 = 157 - 13 \ \Rightarrow\ 9x = 144
  3. 3

    Divide both sides by 9:

    9x9=1449 ⇒ x=16\frac{9x}{9} = \frac{144}{9} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
