Answer 2

Given : -5y/2+7xc+8fg+9 and 4fg+6xc-8​

To Find : Add

Solution:

-5y/2+7xc+8fg+9 and 4fg+6xc-8​

Adding both

-5y/2+7xc+8fg+9 + 4fg+6xc-8​

Combining similar terms

= -5y/2  + 7xc  + 6xc  + 8fg + 4fg + 9 - 8

7xc  + 6xc  = 13xc

8fg + 4fg = 12fg

9 - 8  = 1

=  -5y/2  +12xc  + 12fg + 1

-5y/2+7xc+8fg+9 + 4fg+6xc-8​ =  -5y/2  +12xc  + 12fg + 1
