Explain it step by step in chatMake a short video of it
The lines y = 10x + 8 and y = 48 meet at x = 4-2246810-2020406080100120x = 4y = 10x + 8y = 48
The lines y = 10x + 8 and y = 48 meet at x = 4. 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.

    10x+8=4810x + 8 = 48
  2. 2

    Subtract 8 from both sides:

    10x+8−8=48−8 ⇒ 10x=4010x + 8 - 8 = 48 - 8 \ \Rightarrow\ 10x = 40
  3. 3

    Divide both sides by 10:

    10x10=4010 ⇒ x=4\frac{10x}{10} = \frac{40}{10} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
