The lines y = 9x + 10 and y = 100 meet at x = 10. 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.

    9x+10=1009x + 10 = 100
  2. 2

    Subtract 10 from both sides:

    9x+10−10=100−10 ⇒ 9x=909x + 10 - 10 = 100 - 10 \ \Rightarrow\ 9x = 90
  3. 3

    Divide both sides by 9:

    9x9=909 ⇒ x=10\frac{9x}{9} = \frac{90}{9} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
