Answer:
x - 2y + 7
Step-by-step explanation:
First sum of 3x - 2y + 10 and - y - 15 i. e.
3x - 2y + 10 + (- y - 15)
= 3x - 2y + 10 - y - 15
= 3x - 2y - y + 10 - 15
= 3x - 3y - 5
Then subtraction of 2x - y - 12 from their sum,
3x - 3y - 5 - (2x - y - 12)
= 3x - 3y - 5 - 2x + y + 12
= 3x - 2x - 3y + y - 5 + 12
= x - 2y + 7
Required answer is x - 2y + 7 (Ans)
