Answer 2

-11

Explanation:

`2x - 3y -z`

To evaluate the given expression we plug in the given values

x = −2, y = 3, and z = −2

`2x - 3y - z`

`2(-2) - 3(3) -(-2)`

positive times negative is negative, also negative and negative is positive

Remove the parenthesis by multiplying the numbers

`2(-2) - 3(3) -(-2)`

`-4 -9+2=-11`
