Explain it step by step in chatMake a short video of it
The lines y = 3x + 3 and y = 33 meet at x = 10468101214161520253035404550x = 10y = 3x + 3y = 33
The lines y = 3x + 3 and y = 33 meet at x = 10. 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=333x + 3 = 33
  2. 2

    Subtract 3 from both sides:

    3x+3−3=33−3 ⇒ 3x=303x + 3 - 3 = 33 - 3 \ \Rightarrow\ 3x = 30
  3. 3

    Divide both sides by 3:

    3x3=303 ⇒ x=10\frac{3x}{3} = \frac{30}{3} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
