Question

from the sum of 3x-y+11 and -y-11, subtract 3x-y-11​

Answer 1

Step-by-step explanation:

sum of 3x – y + 11 and -y – 11

= 3x – y + 11 + (-y – 11)

= 3x – y + 11 – y – 11

= 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

= 3x – 3x – 2y + y + 11

= -y + 11

Answer 2

Step-by-step explanation:

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

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

= 3x - y + 11 - y -11

= 3x - 2y

According to question,

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

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

= (-y + 11)
