The lines y = 6x + 15 and y = 93 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.

    6x+15=936x + 15 = 93
  2. 2

    Subtract 15 from both sides:

    6x+15−15=93−15 ⇒ 6x=786x + 15 - 15 = 93 - 15 \ \Rightarrow\ 6x = 78
  3. 3

    Divide both sides by 6:

    6x6=786 ⇒ x=13\frac{6x}{6} = \frac{78}{6} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
