Question : 2a-7b+5c-2,-3a + 2b + 9c-4​

Solution : -a – 5b + 14c - 6

Explanation:

✭Given :

= 2a-7b+5c-2 , -3a +2b + 9c - 4

✭ So when we add,

= 2a- 7b + 5c -2 + (-3a) + 2b + 9c - 4

= 2a - 7b + 5c - 2 - 3a + 2b + 9c -4

✭ We then group the like terms,

= 2a – 3a – 7b +2b + 5c + 9c – 2  - 4

✭ And upon adding we get

= -1a – 5b + 14c - 6

= -a – 5b + 14c - 6
