The lines y = 5x + 3 and y = 93 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.

    5x+3=935x + 3 = 93
  2. 2

    Subtract 3 from both sides:

    5x+3−3=93−3 ⇒ 5x=905x + 3 - 3 = 93 - 3 \ \Rightarrow\ 5x = 90
  3. 3

    Divide both sides by 5:

    5x5=905 ⇒ x=18\frac{5x}{5} = \frac{90}{5} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
