The lines y = 9x + 6 and y = 186 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.

    9x+6=1869x + 6 = 186
  2. 2

    Subtract 6 from both sides:

    9x+6−6=186−6 ⇒ 9x=1809x + 6 - 6 = 186 - 6 \ \Rightarrow\ 9x = 180
  3. 3

    Divide both sides by 9:

    9x9=1809 ⇒ x=20\frac{9x}{9} = \frac{180}{9} \ \Rightarrow\ x = 20
  4. 4

    Check: put x = 20 back into the equation.
