Answer 2

Heya !!!

This is your sum.

Given : 
(4a+b-2c) and (3b+2a+5c)

Arranging according to the similar terms..
 4a  +  b   - 2c
 2a + 3b + 5c
------------------
 6a  + 4b + 3c 

(When (+) and (-) are added, then we subtract the smaller digit from larger, and put the sign of larger digit in the result)

Hence, the answer is 6a + 4b + 3c.

Note : Please look at picture for easy understanding.
