EXPLANATION

Given the algebraic expression:

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

where x = -1 , y = 3 and z = 5

Replacing terms:

=4(-1-2*3+2*5) - (2*-1 + 3*3 -2*5)

Multiplying numbers:

=4(-1-6+10) - (-2 + 9 -10)

Adding numbers:

= 4(3) - (-3)

Removing the parentheses:

= 12 + 3

Adding numbers:

= 15

The answer is 15
