Answer 1

Answer: hey mate answer is -y + 11 .

Step-by-step explanation:

We need to find the sum of 3x-y+11 and -y-11, subtract 3x-y-11.

sum of 3x-y+11 and -y-11

( 3x - y + 11 ) + ( -y - 11 )

 3x - y + 11 - y - 11

Combine like terms.

3x + (-y -y ) + ( 11 - 11 )

3x - 2y

Now subtract 3x-y-11 from 3x-2y.

3x - 2y - ( 3x -y - 11 )

3x - 2y - 3x + y + 11

Combine like terms.

( 3x - 3x ) + ( - 2y + y ) + 11

 - y + 11 .
