**Solution:**

3x^{2} - y^{3} - y^{3} - z [Given]

x = 3, y = -2, and z = -5

Now substitute the values in the given linear equation

= 3 (3)^{2} - (-2)^{3} - (-2)^{3} - (-5)

By further calculation

= 3 (9) - (-8) - (-8) + 5

So we get

= 27 + 8 + 8 + 5

= 48

Therefore, the value of 3x^{2} - y^{3} - y^{3} - z is 48.

**Summary: **

3x^{2} - y^{3} - y^{3} - z if x = 3, y = -2, and z = -5 is 48.
