( a - 8b + 4c ) + ( 2a - 3b + 7c ) + ( 6c - 3a )
= a - 8b + 4c + 2a - 3b + 7c + 6c - 3a
= 3a - 8b + 4c - 3b + 7c + 6c - 3a
= - 8b + 4c - 3b + 7c + 6c [ As 3a & - 3a will cancel each other ]
= - 11b + 17c
= a - 8b + 4c + 2a - 3b + 7c + 6c - 3a
= 3a - 8b + 4c - 3b + 7c + 6c - 3a
= - 8b + 4c - 3b + 7c + 6c [ As 3a & - 3a will cancel each other ]
= - 11b + 17c
