Explain it step by step in chatMake a short video of it
The lines y = 8x + 15 and y = 95 meet at x = 1046810121416406080100120140x = 10y = 8x + 15y = 95
The lines y = 8x + 15 and y = 95 meet at x = 10. 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.

    8x+15=958x + 15 = 95
  2. 2

    Subtract 15 from both sides:

    8x+15−15=95−15 ⇒ 8x=808x + 15 - 15 = 95 - 15 \ \Rightarrow\ 8x = 80
  3. 3

    Divide both sides by 8:

    8x8=808 ⇒ x=10\frac{8x}{8} = \frac{80}{8} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
