The lines y = 11x + 8 and y = 228 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.

    11x+8=22811x + 8 = 228
  2. 2

    Subtract 8 from both sides:

    11x+8−8=228−8 ⇒ 11x=22011x + 8 - 8 = 228 - 8 \ \Rightarrow\ 11x = 220
  3. 3

    Divide both sides by 11:

    11x11=22011 ⇒ x=20\frac{11x}{11} = \frac{220}{11} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
