Explain it step by step in chatMake a short video of it
The lines y = 3x + 15 and y = 33 meet at x = 6246810121520253035404550x = 6y = 3x + 15y = 33
The lines y = 3x + 15 and y = 33 meet at x = 6. 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+15=333x + 15 = 33
  2. 2

    Subtract 15 from both sides:

    3x+15−15=33−15 ⇒ 3x=183x + 15 - 15 = 33 - 15 \ \Rightarrow\ 3x = 18
  3. 3

    Divide both sides by 3:

    3x3=183 ⇒ x=6\frac{3x}{3} = \frac{18}{3} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
