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)
