Find the point of intersection for f(x)\displaystyle {f{{\left({x}\right)}}} and g(x)\displaystyle {g{{\left({x}\right)}}} using the algebraic method in the example above.

{f(x)=x5g(x)=3x5\displaystyle {\left\lbrace\begin{array}{ccc} {f{{\left({x}\right)}}}&=&{x}-{5}\\{g{{\left({x}\right)}}}&=&-{3}{x}-{5}\end{array}\right.}
