Explain it step by step in chatMake a short video of it
The lines y = 6x + 13 and y = 49 meet at x = 624681012102030405060708090x = 6y = 6x + 13y = 49
The lines y = 6x + 13 and y = 49 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.

    6x+13=496x + 13 = 49
  2. 2

    Subtract 13 from both sides:

    6x+13−13=49−13 ⇒ 6x=366x + 13 - 13 = 49 - 13 \ \Rightarrow\ 6x = 36
  3. 3

    Divide both sides by 6:

    6x6=366 ⇒ x=6\frac{6x}{6} = \frac{36}{6} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
