Answer

The expression can be simplified to $4 - 6x$.

Work Step by Step

According to the order of operations, we distribute what is in the inner parentheses first: $$6 - 2[(3x - 3) + 4]$$ Evaluate what is in the inner parentheses: $$6 - 2(3x - 3 + 4)$$ $$6 - 2(3x + 1)$$ Use the distributive property: $$6 - 6x - 2$$ Simplify by combining like terms: $$4 - 6x$$
