To determine

To prove: The solution of the given equation by the use of the graphing calculator if the equations with solutions are as follows,

$\frac{2}{3}+\frac{5}{6}=\frac{x}{9}$ and its solution is $x=\frac{27}{2}$.

$\frac{1}{x}=\frac{1}{4-x}$ and its solution is $x=2$.

$x+\frac{6}{x}=-5$ and its solution is $x=-3\text{ or }x=-2$.

$\frac{3}{x-5}+\frac{1}{x+5}=\frac{2}{x^2-25}$ and its solution is $x=-2$.
