The lines y = 11x + 10 and y = 142 meet at x = 12. 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=14211x + 10 = 142
  2. 2

    Subtract 10 from both sides:

    11x+10−10=142−10 ⇒ 11x=13211x + 10 - 10 = 142 - 10 \ \Rightarrow\ 11x = 132
  3. 3

    Divide both sides by 11:

    11x11=13211 ⇒ x=12\frac{11x}{11} = \frac{132}{11} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
