Answer 3

Solving the Expression -(8-x), -t-(10-x-y), -15x-(-10+2y+7t)

To solve the given expression -(8-x), -t-(10-x-y), -15x-(-10+2y+7t), we'll start by simplifying each part of the expression step by step.

1. Simplify -(8-x): - To simplify -(8-x), we'll distribute the negative sign to both terms inside the parentheses. - -(8-x) = -8 + x

2. Simplify -t-(10-x-y): - To simplify -t-(10-x-y), we'll distribute the negative sign to all terms inside the parentheses. - -t-(10-x-y) = -t - 10 + x + y

3. Simplify -15x-(-10+2y+7t): - To simplify -15x-(-10+2y+7t), we'll distribute the negative sign to all terms inside the parentheses. - -15x-(-10+2y+7t) = -15x + 10 - 2y - 7t

So, the simplified expression is: - -(8-x) = -8 + x - -t-(10-x-y) = -t - 10 + x + y - -15x-(-10+2y+7t) = -15x + 10 - 2y - 7t

These are the simplified forms of the given expression.

Final Simplified Expression:

- -(8-x) = -8 + x - -t-(10-x-y) = -t - 10 + x + y - -15x-(-10+2y+7t) = -15x + 10 - 2y - 7t
