Solve the inequalities : `-3lt=4-(7x)/2lt=18`

Explanation

To solve the inequalities \(-3 \leq 4 - \frac{7x}{2} \leq 18\), we will break it down into two parts and solve each part step by step.

### Step 1: Solve the left inequality
We start with the left part of the inequality:
\[ -3 \leq 4 - \frac{7x}{2} \]
