The lines y = 6x + 13 and y = 109 meet at x = 1610121416182022708090100110120130140150x = 16y = 6x + 13y = 109
The lines y = 6x + 13 and y = 109 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.

    6x+13=1096x + 13 = 109
  2. 2

    Subtract 13 from both sides:

    6x+13−13=109−13 ⇒ 6x=966x + 13 - 13 = 109 - 13 \ \Rightarrow\ 6x = 96
  3. 3

    Divide both sides by 6:

    6x6=966 ⇒ x=16\frac{6x}{6} = \frac{96}{6} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
