Explain it step by step in chatMake a short video of it
The lines y = 5x + 5 and y = 40 meet at x = 72468101210203040506070x = 7y = 5x + 5y = 40
The lines y = 5x + 5 and y = 40 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.

    5x+5=405x + 5 = 40
  2. 2

    Subtract 5 from both sides:

    5x+5−5=40−5 ⇒ 5x=355x + 5 - 5 = 40 - 5 \ \Rightarrow\ 5x = 35
  3. 3

    Divide both sides by 5:

    5x5=355 ⇒ x=7\frac{5x}{5} = \frac{35}{5} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
