Answer:
(-y-11)
Step-by-step explanation:
Lets do the sum first--->
(3x-y-11) and (-y - 11)
= 3x -y -11 -y -11
= 3x -2y -22
Now lets subtract (3x – y-11) from it
= 3x - 2y -22 -(3x-y-11)
= 3x -2y -22 -3x +y +11
= -y -11
Alternative / Quick Method---->
If we observe, (3x – y-11) is there in the 2 terms of adding and then it is the one which has to be subtracted. So that gets cut off, and the other out of the 2 terms left will be the answer, which (-y-11)
