Answer:

The value of the provide expression is -7.

Step-by-step explanation:

Consider the provided expression.

[tex] 4x - y - 2z [/tex]

We need to find the value of the expression, for x = -2, y = 3, and z = -2.

Substitute the respective values in the provided expression.

[tex] 4(-2) - 3 - 2(-2) [/tex]

[tex] -8 - 3 +4 [/tex]

[tex] -11 +4 [/tex]

[tex] -7 [/tex]

Hence, the value of the provide expression is -7.
