Answer 1

square both sides
11x=9x+2
2x=3
x=1

Answer 2

2x=2

Answer 3

sorry

Answer 4

\[\large \sqrt{11x}=3\sqrt{x+2}\]


\[\large (\sqrt{11x})^2=(3\sqrt{x+2})^2\]


\[\large 11x=9(x+2)\]


\[\large 11x=9x+18\]


\[\large 11x-9x=18\]


\[\large 2x=18\]


\[\large x=\frac{18}{2}\]


\[\large x=9\]
