The lines y = 5x + 12 and y = 97 meet at x = 17. 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.

    5x+12=975x + 12 = 97
  2. 2

    Subtract 12 from both sides:

    5x+12−12=97−12 ⇒ 5x=855x + 12 - 12 = 97 - 12 \ \Rightarrow\ 5x = 85
  3. 3

    Divide both sides by 5:

    5x5=855 ⇒ x=17\frac{5x}{5} = \frac{85}{5} \ \Rightarrow\ x = 17
  4. 4

    Check: put x = 17 back into the equation.
