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,

$\frac{3}{4}+\frac{5}{8}=\frac{x}{12}$ and its solution is $x=\frac{33}{2}$.

$\frac{1}{x}=\frac{1}{6-x}$ and its solution is $x=3$.

$\frac{x^2}{x+2}=\frac{4}{x+2}$ and its solution is $x=2$.

$\frac{4}{x-2}+\frac{1}{x+2}=\frac{26}{x^2-4}$ and its solution is $x=4$.
