To solve for \( x \) and \( y \) in the given system of equations, let's start by setting up the equations:

1. \( 2x - y = 17 \)
2. \( 4y + 3x = 9 \)

Let's go through the steps to solve these equations.

### Step 1: Solve one of the equations for \( y \) or \( x \)

Let's start by isolating \( y \) in the first equation.

\[
2x - y = 17
\]
\[
y = 2x - 17
\]

### Step 2: Substitute \( y \) in the second equation

Now that we have \( y = 2x - 17 \), substitute this into the second equation:

\[
4(2x - 17) + 3x = 9
\]

Expanding and simplifying:

\[
8x - 68 + 3x = 9
\]
\[
11x - 68 = 9
\]
\[
11x = 77
\]
\[
x = 7
\]

### Step 3: Substitute \( x = 7 \) back into the equation for \( y \)

Now, substitute \( x = 7 \) into \( y = 2x - 17 \):

\[
y = 2(7) - 17
\]
\[
y = 14 - 17
\]
\[
y = -3
\]

### Solution

The solution to the system is:
\[
x = 7, \quad y = -3
\]
