Answer 3

Problem Statement

The given expression is: 2(x+4)-(1-x)-(1+2)x-2. We need to expand the brackets and combine like terms.

Solution

To expand the brackets and combine like terms, let's simplify the given expression step by step:

Step 1: Expand the brackets. - 2(x+4) = 2x + 8 - -(1-x) = -1 + x - -(1+2)x = -x - 2x = -3x

The expression becomes: 2x + 8 - (-1 + x) - (-3x) - 2.

Step 2: Simplify the expression by combining like terms. - 2x + 8 - (-1 + x) - (-3x) - 2 = 2x + 8 + 1 - x + 3x - 2.

Step 3: Combine like terms. - 2x + 8 + 1 - x + 3x - 2 = (2x - x + 3x) + (8 + 1 - 2) = 4x + 7.

Therefore, the simplified expression is 4x + 7.
