The lines y = 11x + 12 and y = 210 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.

    11x+12=21011x + 12 = 210
  2. 2

    Subtract 12 from both sides:

    11x+12−12=210−12 ⇒ 11x=19811x + 12 - 12 = 210 - 12 \ \Rightarrow\ 11x = 198
  3. 3

    Divide both sides by 11:

    11x11=19811 ⇒ x=18\frac{11x}{11} = \frac{198}{11} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
