Explain it step by step in chatMake a short video of it
The lines y = 6x + 13 and y = 25 meet at x = 2-4-22468-10102030405060x = 2y = 6x + 13y = 25
The lines y = 6x + 13 and y = 25 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.

    6x+13=256x + 13 = 25
  2. 2

    Subtract 13 from both sides:

    6x+13−13=25−13 ⇒ 6x=126x + 13 - 13 = 25 - 13 \ \Rightarrow\ 6x = 12
  3. 3

    Divide both sides by 6:

    6x6=126 ⇒ x=2\frac{6x}{6} = \frac{12}{6} \ \Rightarrow\ x = 2
  4. 4

    Check: put x = 2 back into the equation.
