The lines y = 11x + 10 and y = 120 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.

    11x+10=12011x + 10 = 120
  2. 2

    Subtract 10 from both sides:

    11x+10−10=120−10 ⇒ 11x=11011x + 10 - 10 = 120 - 10 \ \Rightarrow\ 11x = 110
  3. 3

    Divide both sides by 11:

    11x11=11011 ⇒ x=10\frac{11x}{11} = \frac{110}{11} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
