The image shows a problem where we need to solve for the values of \( x \) and \( z \) given two pairs of vertical angles.

### The equations are based on the properties of vertical angles:
1. Vertical angles are equal, meaning that:
   \[
   (6x + 7)^\circ = (5x - 14)^\circ
   \]

2. Also, the angle labeled \( z^\circ \) is vertically opposite the angle labeled \( (6x + 7)^\circ \), so:
   \[
   z^\circ = (6x + 7)^\circ
   \]

### Step 1: Solve for \( x \)
We start with the equation:
\[
6x + 7 = 5x - 14
\]

Subtract \( 5x \) from both sides:
\[
x + 7 = -14
\]

Now subtract 7 from both sides:
\[
x = -21
\]

### Step 2: Solve for \( z \)
Since \( z = 6x + 7 \), substitute \( x = -21 \) into the equation for \( z \):
\[
z = 6(-21) + 7 = -126 + 7 = -119
\]

Thus, the values are:
\[
x = -21, \quad z = -119
\]
