The solution of 3x + 6 = 6 is x = 0.

Explain it step by step in chatMake a short video of it
The lines y = 3x + 6 and y = 6 meet at x = 0-6-4-2246-15-10-5510152025x = 0y = 3x + 6y = 6
The lines y = 3x + 6 and y = 6 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+6=63x + 6 = 6
  2. 2

    Subtract 6 from both sides:

    3x+6−6=6−6 ⇒ 3x=03x + 6 - 6 = 6 - 6 \ \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.
