Answer:
Sum of 3x – y + 11 and -y – 11
= (3x – y + 11) + (-y – 11)
= 3x – y + 11 – y – 11
∴ 3x – 2y – (3x – 2y) – (3x – y – 11)
= 3x – 2y – 3x + y + 11
= 3x – 3x – 2y + y + 11
= -y + 11 is required solution
Answer:
Sum of 3x – y + 11 and -y – 11
= 3x + y - 22
Subtracting 3x - y - 11 from 3x + y -22
= xy
