Solution set:$ \qquad\{ 5 \}$

Work Step by Step

Graphing with desmos.com/calculator (see image) graph the LHS function and the RHS function in the same window. We find the intersection point to be $(5,13),$ meaning that for x=$5$ the LHS equals the RHS, meaning that x=$5$ is the solution of the equation. Solution set:$ \qquad\{ 5 \}$
