3k-4y+2b-(-y)
-6p+2a+4p-6a
-p-k-a+2a+k
4h-8f+2f-12h
5a-4k-10a-(-2a)

Answer 1

1. 3k-4y+2b-(-y) = 3k+2b-4y+y = 3k+2b-3y = 3k-3y+2b = 3(k-y)+2b

2. -6p+2a+4p-6a = -6p+4p+2a-6a = -2p-4a = -2(p+2a)

3. -p-k-a+2a+k = -k+k-a+2a-p = a-p

4. 4h-8f+2f-12h = 4h-12h-8f+2f = -8h-6f = -2(4h+3f)

5. 5a-4k-10a-(-2a) = -4k+5a-10a+2a = -4k-3a
