From the sum of 3x – 2y - 5 and 7x + 3y - 2, subtract the sum of
5x + 3y - 1 and 4x + 4y + 5.​

Answer 1

Answer:

First the sum of :

3x-2y-5 and 7x+3y-2

3x-2y-5+7x+3y-2

3x+7x-2y+3y-5-2

10x+y-7

Now the sum of:

5x+3y-1 and 4x+4y+5

5x+3y-1+4x+4y+5

5x+4x+3y+4y-1+5

9x+7y+4

So ,

10x+y-7 - (9x+7y+4)

10x+y-7 - 9x -7y-4

10x-9x+y-7y-7-4

x-6y-11

So the answer is x-6y-11
