Explain it step by step in chatMake a short video of it
The lines y = 7x + 13 and y = 62 meet at x = 72468101220406080100x = 7y = 7x + 13y = 62
The lines y = 7x + 13 and y = 62 meet at x = 7. 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.

    7x+13=627x + 13 = 62
  2. 2

    Subtract 13 from both sides:

    7x+13−13=62−13 ⇒ 7x=497x + 13 - 13 = 62 - 13 \ \Rightarrow\ 7x = 49
  3. 3

    Divide both sides by 7:

    7x7=497 ⇒ x=7\frac{7x}{7} = \frac{49}{7} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
