1. Answer :-

   In this question, we first need to find the sum of ( 3x + y + 11 ) and ( – y – 11 ). After getting the sum, we need to subtract ( 3x – 2y – 11 ).

   Sum of ( 3x + y + 11 ) and ( – y – 11 )

   → ( 3x + y + 11 ) + ( – y – 11 )

   Opening the bracket –

   → 3x + y + 11 – y – 11

   Arranging like terms :-

   → 3x + ( y – y ) + ( 11 – 11 )

   Solving the expression –

   → 3x + 0 + 0

   → 3x

   Subtracting ( 3x – 2y – 11 ) from 3x

   → 3x – ( 3x – 2y – 11 )

   Opening the bracket :-

   → 3x – 3x + 2y + 11

   Arranging like terms :-

   → ( 3x – 3x ) + 2y + 11

   Solving the expression :-

   → 2y + 11

2. Answer:

   2y + 11

   Step-by-step explanation:

   Sum of 3x+y+11 and (-y-11) = 3x + y + 11 + (-y – 11) = 3x + y + 11 – y – 11 = 3x

   Subtraction of 3x-2y-11 from the sum of 3x+y+11 and (-y-11) = 3x – (3x – 2y – 11) = 3x – 3x + 2y + 11 = 2y + 11
