Final answer:
To simplify the expression (-x+1)-(3x+8), distribute the negative sign to the terms inside the parentheses, then combine the like terms. The simplified expression is -4x - 7.
Step-by-step explanation:
The expression given is (-x+1)-(3x+8). To simplify this expression, we remove the parentheses and combine like terms. Here's the step-by-step process:
- First, distribute the negative sign to the terms inside the second set of parentheses: -x + 1 - 3x - 8.
- Combine the like terms, which are -x and -3x to get -4x, and 1 and -8 to get -7.
- The simplified expression now reads -4x - 7.
Remember, when you have a negative sign in front of parentheses, you must distribute it to each term inside the parentheses before combining like terms.
