Explain it step by step in chatMake a short video of it
The lines y = 12x + 13 and y = 37 meet at x = 2-4-22468-40-2020406080100120x = 2y = 12x + 13y = 37
The lines y = 12x + 13 and y = 37 meet at x = 2. 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.

    12x+13=3712x + 13 = 37
  2. 2

    Subtract 13 from both sides:

    12x+13−13=37−13 ⇒ 12x=2412x + 13 - 13 = 37 - 13 \ \Rightarrow\ 12x = 24
  3. 3

    Divide both sides by 12:

    12x12=2412 ⇒ x=2\frac{12x}{12} = \frac{24}{12} \ \Rightarrow\ x = 2
  4. 4

    Check: put x = 2 back into the equation.
