M 20w-12w+4w-3w
N 11m-8m-2m

Answer 1

E) 9t+12t-10t=

21t - 10t

11t

G) 19ab-10ab+5ab=

24ab - 10ab

14ab

H) 20m-12m+7m=

27m - 12m

15m

I) 13x-10x+2x+4x=

19x - 10x

9x

J) 10xy+12xy-21xy=

22xy - 21xy

1xy

K) 25y-12y+13y=

38y - 12y

26y

M) 20w-12w+4w-3w

24w - 15w

9w

N) 11m-8m-2m

11m - 10m

1m
