This problem is a simple substitution problem.
You have x2yz + x + y and you are given the following pieces of information:
x = 1, y = -3 and z = 3.
1. You simply substitute these values into the polynomial.

x y z x y
(1)2(-3)(3) + (1) + (-3)

2. Simplify.

1*2*-3*3 + 1 -3 = -20

-20 is your answer!
