Answer:
-4 - 17x
Step-by-step explanation:
Anything enclosed in parentheses must be done first if possible. (3x + 2) is inside two sets of parentheses, but nothing can be done with 3x + 2.
Multiplication must be done next. [6(3x+2)-x] becomes 18x + 12 - x, or
17x + 12.
Now we have 4 - 17x - 12 + 4. Combining like terms through addition and subtraction, we get 4 - 12 + 4 - 17x, or -4 - 17x.
