ANSWER
-24
EXPLANATION
We have the expression and we want to find its value when b is 2 and c is -3.
To do that, we replace b in the expression with 2 and c with -3.
The expression is:
-4b + 8c + 12 - 8b - 2c + 6
So, we have:
-4(2) + 8(-3) + 12 - 8(2) - 2(-3) + 6
=> -8 - 24 + 12 - 16 + 6 + 6
=> -24
That is the answer.
