$\left( -\infty,-4 \right)\cup\left( -2,\infty \right)$

Work Step by Step

Solving the inequalities separately results to \begin{array}{l} x+4<0\\ x-12\\ x>-2 .\end{array} Using the conjuntion "or", the solution set is the combined solutions sets of both inequalities. Hence, the solution set is $ \left( -\infty,-4 \right)\cup\left( -2,\infty \right) $.
