Answer 1

Hi mate

here is ur answer...⬇⬇⬇⬇⬇⬇

1st we want to add

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

= 4a - 5b +7c - 9 .....(I)

6b - 6c + 12 + a - b + c - 4 = 5b - 5c + a + 8 ...(ii)

now ,

subtract

5b - 5c + a + 8 - ( 4a - 5b + 7c -9) = 5b - 5c + a + 8 - 4a + 5b - 7c +9

= 10b - 12c - 3a + 17

I hope this will help u.....
