Explain it step by step in chatMake a short video of it
The lines y = 10x + 10 and y = 50 meet at x = 4-2246810-2020406080100120x = 4y = 10x + 10y = 50
The lines y = 10x + 10 and y = 50 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+10=5010x + 10 = 50
  2. 2

    Subtract 10 from both sides:

    10x+10−10=50−10 ⇒ 10x=4010x + 10 - 10 = 50 - 10 \ \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.
