Explain it step by step in chatMake a short video of it
The lines y = 11x + 9 and y = 53 meet at x = 4-2246810-2020406080100120x = 4y = 11x + 9y = 53
The lines y = 11x + 9 and y = 53 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.

    11x+9=5311x + 9 = 53
  2. 2

    Subtract 9 from both sides:

    11x+9−9=53−9 ⇒ 11x=4411x + 9 - 9 = 53 - 9 \ \Rightarrow\ 11x = 44
  3. 3

    Divide both sides by 11:

    11x11=4411 ⇒ x=4\frac{11x}{11} = \frac{44}{11} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
