Intermediate Algebra for College Students (7th Edition)

Solution set:$\qquad\{ 3 \}_{ }$
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 $(3,19),$ meaning that for x=$3$ the LHS equals the RHS, meaning that x=$3$ is the solution of the equation.
