Answer 2

Step-by-step explanation:

3a+3b+c=-20 --(1)

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

8a-2b+3c=5 ----(3)

from equ(2)

a-3b+2c=9

a=9+3b-2c

put a in equ(1)&(3)

3a+3b+c=-20

3(9+3b-2c)+3b+c=-20

27+9b-6c+3b+c=-20

12b-5c=-47 --(4)

8a-2b+3c=5

8(9+3b-2c)-2b+3c=5

72+24b-16c-2b+3c=5

22b-13c=-67---(5)

solve equ(4)&(5) simultaneously

and get d value for b and c

then substitute it in

a=9+3b-2c

I would appreciate if my answer is chosen as a brainliest answer
