The given system of equations is:

1) \( 2x + 3y = 5 \)  
2) \( 5x - 2y = -16 \)

Let's solve this system of linear equations using either substitution or elimination. I'll use the elimination method.

### Step 1: Eliminate one variable
To eliminate a variable, we need to multiply the equations so that the coefficients of one variable (either \( x \) or \( y \)) become the same. Let's eliminate \( y \).

We can multiply the first equation by 2 and the second equation by 3 to match the coefficients of \( y \):

\[
(2x + 3y = 5) \times 2 \Rightarrow 4x + 6y = 10
\]
\[
(5x - 2y = -16) \times 3 \Rightarrow 15x - 6y = -48
\]

Now, we have the system:
\[
4x + 6y = 10 \tag{3}
\]
\[
15x - 6y = -48 \tag{4}
\]

### Step 2: Add the equations
Now, we add equations (3) and (4) to eliminate \( y \):

\[
(4x + 6y) + (15x - 6y) = 10 + (-48)
\]
\[
4x + 15x = -38
\]
\[
19x = -38
\]

Solve for \( x \):

\[
x = \frac{-38}{19} = -2
\]

### Step 3: Substitute \( x = -2 \) into one of the original equations
Substitute \( x = -2 \) into equation (1) to find \( y \):

\[
2(-2) + 3y = 5
\]
\[
-4 + 3y = 5
\]
\[
3y = 5 + 4 = 9
\]
\[
y = \frac{9}{3} = 3
\]

### Final Solution:
The solution to the system of equations is:
\[
x = -2, \quad y = 3
\]
