Explain it step by step in chatMake a short video of it
The lines y = 5x + 9 and y = 49 meet at x = 8246810121420304050607080x = 8y = 5x + 9y = 49
The lines y = 5x + 9 and y = 49 meet at x = 8. 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+9=495x + 9 = 49
  2. 2

    Subtract 9 from both sides:

    5x+9−9=49−9 ⇒ 5x=405x + 9 - 9 = 49 - 9 \ \Rightarrow\ 5x = 40
  3. 3

    Divide both sides by 5:

    5x5=405 ⇒ x=8\frac{5x}{5} = \frac{40}{5} \ \Rightarrow\ x = 8
  4. 4

    Check: put x = 8 back into the equation.
