Answer 2

5x+3y=8,3x+5y=8
6x-7y=5,x+2y=4
10x-8y=14,x+y=5
4x+7y=3,x+y=0
3x+y=10,7x-y=20
44x+10y=27,x+y=1
8x-y=0,x+y=18
11x-y=12,11y-x=-12
5x+6y=27,2x+3y=12
7x-2y=4,x+2y=12
(2x+y)-5y=2,2x-5y=0
7x-3y=3,3x+2y=21
7x+2y=21,y-6x=1
10x-8y=0,3x-2y=2
3x+y=10,5x-7y=8

Answer 3

8x+5y=10,2x+5y=6 ; 5y-7x=3,3x+2y=9 ; 3y-2x=7,5x+3=8
