The solution of 11x + 7 = 7 is x = 0.

Explain it step by step in chatMake a short video of it
The lines y = 11x + 7 and y = 7 meet at x = 0-6-4-2246-60-40-2020406080x = 0y = 11x + 7y = 7
The lines y = 11x + 7 and y = 7 meet at x = 0. 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+7=711x + 7 = 7
  2. 2

    Subtract 7 from both sides:

    11x+7−7=7−7 ⇒ 11x=011x + 7 - 7 = 7 - 7 \ \Rightarrow\ 11x = 0
  3. 3

    Divide both sides by 11:

    11x11=011 ⇒ x=0\frac{11x}{11} = \frac{0}{11} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
