The lines y = 5x + 15 and y = 95 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.

    5x+15=955x + 15 = 95
  2. 2

    Subtract 15 from both sides:

    5x+15−15=95−15 ⇒ 5x=805x + 15 - 15 = 95 - 15 \ \Rightarrow\ 5x = 80
  3. 3

    Divide both sides by 5:

    5x5=805 ⇒ x=16\frac{5x}{5} = \frac{80}{5} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
