1. 3a-4b,4a+2b
2. 5x+2y,-7x+y
3.3ab+2bc,-5ab+3bc,2ab-5bc
4.2x-10y,9y-12x,x+y
5.3m-20n,12m-7n,-8m+12n

​

Answer 1

Answer:

1.) 3a-4b+4a+2b= 3a+4a+2b-4b=7a-2b

2.)5x+2y-7x+y=5x-7x+2y+y=-2x+3y

3.) 3ab+2bc-5ab+3bc+2ab-5bc=3ab-5ab+2ab+2bc+3bc-5bc=0 ab +0 bc = 0

4.) 3m-20n+12m-7n-8m+12n=3m+12m-8m-20n-7n+12n=7m-15 n
