Answer 1

1. -4-а+5-b=-а-b+1
2. -х +4 -у+5=-х-у+9
3 -2х+5+6-3m=-2х-3m+11
4 -3+4k-1-2+4-m=-2+4k-m

Answer 2

Simplifying the Expression

To simplify the given expression -(4a) + (5-b) - (-x+4) - (y-5) - (2x-5) - (-6+3m) - (-3+4k-1) - (2-4+m), let's break it down step by step:

1. Distribute the negative sign to each term inside the parentheses: -(-4a) + (5-b) - (-x+4) - (y-5) - (2x-5) - (-6+3m) - (-3+4k-1) - (2-4+m)

2. Simplify each term inside the parentheses: -(-4a) simplifies to 4a -(-x+4) simplifies to x-4 -(-6+3m) simplifies to 6-3m -(-3+4k-1) simplifies to 3-4k+1 -(-4+m) simplifies to 4-m

3. Combine like terms: 4a + (5-b) - (x-4) - (y-5) - (2x-5) - (6-3m) - (3-4k+1) - (2-4+m)

4. Simplify further: 4a + 5 - b - x + 4 - y + 5 - 2x + 5 - 6 + 3m - 3 + 4k - 1 - 2 + 4 - m

5. Combine like terms: 4a - b - x + 4 - y + 5 - 2x + 5 - 6 + 3m - 3 + 4k - 1 - 2 + 4 - m

6. Simplify further: 4a - b - 3x - y + 3m + 4k + 6 - m + 12

7. Combine like terms: 4a - b - 3x - y + 3m + 4k + 6 - m + 12

8. Simplify further: 4a - b - 3x - y + 2m + 4k + 18

Therefore, the simplified expression is 4a - b - 3x - y + 2m + 4k + 18.
