The lines y = 5x + 10 and y = 110 meet at x = 20. 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+10=1105x + 10 = 110
  2. 2

    Subtract 10 from both sides:

    5x+10−10=110−10 ⇒ 5x=1005x + 10 - 10 = 110 - 10 \ \Rightarrow\ 5x = 100
  3. 3

    Divide both sides by 5:

    5x5=1005 ⇒ x=20\frac{5x}{5} = \frac{100}{5} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
