The lines y = 3x + 6 and y = 60 meet at x = 18. 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.

    3x+6=603x + 6 = 60
  2. 2

    Subtract 6 from both sides:

    3x+6−6=60−6 ⇒ 3x=543x + 6 - 6 = 60 - 6 \ \Rightarrow\ 3x = 54
  3. 3

    Divide both sides by 3:

    3x3=543 ⇒ x=18\frac{3x}{3} = \frac{54}{3} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
