Solve \(\displaystyle 5 - 4 x < 19\). Write the solution in interval notation.
Isolating \(\displaystyle x\) gives \(\displaystyle - 4 x<14\). Dividing off the \(\displaystyle x\) coefficient and reversing the inequality symbol because its negative gives \(\displaystyle x>- \frac{7}{2}\). The solution is \(\displaystyle \left(- \frac{7}{2}, \infty\right)\)
