3. Solve the system of equations:

$$
\left\{\begin{array}{l}
3 x y-5 y z-x z=3 y \\
x y+y z=-y \\
-5 x y+4 y z+x z=-4 y
\end{array}\right.
$$
Answer: $(\mathbf{2},-\mathbf{1} / \mathbf{3},-3),(x, 0,0),(0,0, z)$, where $x, z-$ are any real numbers.

Solution: a similar solution to this problem is present in variant 1 under the same number.
