Answer 2

Let's simplify the given expressions step by step:

1. $3b - (5a - 7b)$: Distribute the negative sign inside the parentheses: $3b - 5a + 7b$ Combine like terms: $10b - 5a$

2. $-3q - (8p - 3q)$: Distribute the negative sign inside the parentheses: $-3q - 8p + 3q$ Combine like terms: $-8p$

3. $-(8c - 4) + 4$: Distribute the negative sign inside the parentheses: $-8c + 4 + 4$ Combine like terms: $-8c + 8$

4. $-(-2a - 4) - (3 + 5a)$: Negate the terms inside the first set of parentheses: $2a + 4 - (3 + 5a)$ Distribute the negative sign inside the second set of parentheses: $2a + 4 - 3 - 5a$ Combine like terms: $-3a + 1$

5. $(5 - 3b) + (-3b - 11)$: Distribute the negative sign inside the second set of parentheses: $5 - 3b - 3b - 11$ Combine like terms: $5 - 6b - 11$ Combine constants: $-6b - 6$

So, the simplified expressions are:

1. $10b - 5a$
2. $-8p$
3. $-8c + 8$
4. $-3a + 1$
5. $-6b - 6$
