Let's solve for q:
[tex]\begin{gathered} -4+4-\frac{1}{2}q\leq33-q-4 \\ -\frac{1}{2}\text{q}\leq29-q \\ \text{Then, you add q to both sides of the inequality} \\ q-\frac{1}{2}q\leq29-q+q \\ \frac{1}{2}q\leq29 \\ \text{Now, we multiply both sides of the inequality by 2} \\ 2\times\frac{1}{2}q\leq29\times2 \\ q\leq58 \end{gathered}[/tex]
