Answer 2

To simplify the expression 3(x - 2) - (x + 2) - 2x + (x - 1), we can use the distributive property and combine like terms. Let's break it down step by step:

Step 1: Distribute the 3 to the terms inside the parentheses: 3(x - 2) - (x + 2) - 2x + (x - 1) = 3x - 6 - (x + 2) - 2x + (x - 1)

Step 2: Simplify the terms inside the parentheses: = 3x - 6 - x - 2 - 2x + x - 1

Step 3: Combine like terms: = (3x - x - 2x + x) - 6 - 2 - 1

Step 4: Further simplify: = x - 9

Therefore, the simplified form of the expression 3(x - 2) - (x + 2) - 2x + (x - 1) is x - 9.
