The solution of 3x + 3 = 6 is x = 1.

Explain it step by step in chatMake a short video of it
The lines y = 3x + 3 and y = 6 meet at x = 1-4-2246-15-10-5510152025x = 1y = 3x + 3y = 6
The lines y = 3x + 3 and y = 6 meet at x = 1. 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+3=63x + 3 = 6
  2. 2

    Subtract 3 from both sides:

    3x+3−3=6−3 ⇒ 3x=33x + 3 - 3 = 6 - 3 \ \Rightarrow\ 3x = 3
  3. 3

    Divide both sides by 3:

    3x3=33 ⇒ x=1\frac{3x}{3} = \frac{3}{3} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.
