Answer 1

Given:

3x-2y+10 , -y-15 , 2x-y-12

To find:

Subtract 2x-y-12 from the sum of 3x-2y+10 and -y-15.

Solution:

Addition of 3x-2y+10 and -y-15

    3x - 2y + 10

 +      - y    - 15  

  3x - 3y - 5

Subtract 2x-y-12 from the sum of 3x-2y+10 and -y-15

Sum =  3x - 3y - 5

    3x - 3y - 5

    2x - y   - 12

 (-)    (+)   (+)    

     x - 2y + 7

So, we get x-2y+7
