\[
\min_{x} \ z = -5x_1 - 7x_2 - 12x_3 + x_4
\]

**Subject to the Constraints:**
1. $ 2x_1 + 3x_2 + 2x_3 + x_4 \leq 38 $
2. $ 3x_1 + 2x_2 + 4x_3 - x_4 \leq 55 $

**Non-negativity Constraints:**
\[ x_1, x_2, x_3, x_4 \geq 0 \]

**Initial Solution:**
\[ x_{\text{ini}} = (0, 0, 0, 0)^T \]

### Explanation

This problem involves minimizing a linear objective function subject to a set of linear inequalities and non-negativity constraints. The initial solution vector is $(0, 0, 0, 0)$. The simplex method will be applied to find the optimal solution that minimizes the objective function while satisfying all the given constraints.
