Let's test the consistency of the system of equations and solve it if it's consistent. The system is:

\[
\begin{aligned}
    3x - y - 2z &= 2 \quad \text{(1)} \\
    2y - z &= -1 \quad \text{(2)} \\
    3x - 5y &= 3 \quad \text{(3)}
\end{aligned}
\]

### Step 1: Solve for \( z \) from Equation (2)

From Equation (2):

\[
2y - z = -1 \implies z = 2y + 1 \quad \text{(4)}
\]

### Step 2: Substitute \( z = 2y + 1 \) into Equation (1)

Substitute \( z = 2y + 1 \) from (4) into (1):

\[
3x - y - 2(2y + 1) = 2
\]
\[
3x - y - 4y - 2 = 2
\]
\[
3x - 5y - 2 = 2 \implies 3x - 5y = 4 \quad \text{(5)}
\]

### Step 3: Compare with Equation (3)

Notice that Equation (5) is the same as Equation (3):

\[
3x - 5y = 3
\]
and
\[
3x - 5y = 4
\]

These two equations contradict each other. One equation states \( 3x - 5y = 3 \) while the other states \( 3x - 5y = 4 \). Therefore, **the system is inconsistent** and has no solution.

### Conclusion:
The system of equations is inconsistent, so there is **no solution**.

Test the consistency of the following system and solve if they are consistent: 3x - y - 2z = 2, 2y - z = -1, 3x - 5y = 3.
