Explain it step by step in chatMake a short video of it
The lines y = 3x + 12 and y = 12 meet at x = 0-6-4-2246-551015202530x = 0y = 3x + 12y = 12
The lines y = 3x + 12 and y = 12 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.

    3x+12=123x + 12 = 12
  2. 2

    Subtract 12 from both sides:

    3x+12−12=12−12 ⇒ 3x=03x + 12 - 12 = 12 - 12 \ \Rightarrow\ 3x = 0
  3. 3

    Divide both sides by 3:

    3x3=03 ⇒ x=0\frac{3x}{3} = \frac{0}{3} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
