Explain it step by step in chatMake a short video of it
The lines y = 5x + 13 and y = 58 meet at x = 946810121430405060708090x = 9y = 5x + 13y = 58
The lines y = 5x + 13 and y = 58 meet at x = 9. 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.

    5x+13=585x + 13 = 58
  2. 2

    Subtract 13 from both sides:

    5x+13−13=58−13 ⇒ 5x=455x + 13 - 13 = 58 - 13 \ \Rightarrow\ 5x = 45
  3. 3

    Divide both sides by 5:

    5x5=455 ⇒ x=9\frac{5x}{5} = \frac{45}{5} \ \Rightarrow\ x = 9
  4. 4

    Check: put x = 9 back into the equation.
