Explain it step by step in chatMake a short video of it
The lines y = 12x + 9 and y = 9 meet at x = 0-6-4-2246-60-40-2020406080x = 0y = 12x + 9y = 9
The lines y = 12x + 9 and y = 9 meet at x = 0. 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.

    12x+9=912x + 9 = 9
  2. 2

    Subtract 9 from both sides:

    12x+9−9=9−9 ⇒ 12x=012x + 9 - 9 = 9 - 9 \ \Rightarrow\ 12x = 0
  3. 3

    Divide both sides by 12:

    12x12=012 ⇒ x=0\frac{12x}{12} = \frac{0}{12} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
