Question

8a-3b+11c,5b-6a+7c and 9c+2a-8b​

Answer 1

Explanation:

Given that:

x=8a - 3b + 11c,

y=5b - 6a + 7c

and  

z=9c + 2a - 8b

solution:-

Here

x + y + z = (8a - 3b + 11c) + (5b - 6a + 7c) + (9c + 2a - 8b) 

= [ 8a - 3b + 11c + 5b - 6a + 7c + 9c + 2a - 8b ]

= [ (8a - 6a + 2a ) + ( 5b - 3b - 8b) + (11c + 7c +9c) ] 

= ( 4a - 6b + 27c ) Answer
