Answer
The solution set is the set of real numbers, which means that any real number satisfies the given equation.
Work Step by Step
Simplify both sides of the equation by using the distributive property then combining like terms to have:
$\\\\2m-12-m=4m-12-3m
\\\\m-12=m-12$
$\\\\\\$Subtract $m$ to both sides to have:
$\\\\-12=-12$
$\\\\\\$This statement is true therefore the given equation is an identity.
$\\\\\\$Thus, any real number will satisfy the given equation.
