Answer:

(i).slove= 3mn+(- 5mn)+8mn+(- 4mn)

3mn-5mn+8mn-4mn

11mn-9mn

2mn

(ii).solve= t-8tz,3tz-z,z-t

t-t-8tz+3tz-z+z

-5tz

(iii).slove=-7mn+5,12mn+2,9mn-8,-2mn-3

-7mn+9mn+12mn-2mn+5+2-8+3

-9mn+9mn+12mn+7-11

12mn-4

(iv).slove=a+b-3,b-a+3,a-b+3

a-a+a+b+b-b-3+3+3

a+b+3

(v).slove=14x+10y-12xy-13,18+7x10y+8xy+4xy

14x+7x+10y-10y-12xy+8xy+4xy-13+18

21x+5

(vi).solve=5m-7n+3n-4m+2+2m-3mn-5

5m-4m+2m-7n+3n-3mn-5+2

4m-4n-3mn-3

(vii).slove=4x²y-3xy²-5xy²+5x²y

4x²y+5x²y-3xy²-5xy²

9x²y-8xy²
