Answer:

• 5b +3r -1
• 2k +5
• -13k +2

Explanation:

It looks like you want to simplify the sums.

1. (3r -4) -(-5b -3) = 3r -4 +5b +3 = 5b +3r +(-4+3)

= 5b +3r -1

__

2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)

= 2k +5

__

3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)

= -13k +2
