Explain it step by step in chatMake a short video of it
The lines y = 11x + 15 and y = 26 meet at x = 1-4-2246-40-2020406080100x = 1y = 11x + 15y = 26
The lines y = 11x + 15 and y = 26 meet at x = 1. 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+15=2611x + 15 = 26
  2. 2

    Subtract 15 from both sides:

    11x+15−15=26−15 ⇒ 11x=1111x + 15 - 15 = 26 - 15 \ \Rightarrow\ 11x = 11
  3. 3

    Divide both sides by 11:

    11x11=1111 ⇒ x=1\frac{11x}{11} = \frac{11}{11} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.
