Let 1/y=m
2x-3m=9...(1)*3
3x+7m=2...(2)*2
———————-
6x-9m=27
6x+14m=4
——————-
-23m=23
M=23/(-23)=-1
Put m=-1 in 2x-3m=9
2x-3*(-1)=9
2x+3=9
2x=9-3
X=6/2=3
X=3
M=-1
1/y=-1
Y=-1
2x-3m=9...(1)*3
3x+7m=2...(2)*2
———————-
6x-9m=27
6x+14m=4
——————-
-23m=23
M=23/(-23)=-1
Put m=-1 in 2x-3m=9
2x-3*(-1)=9
2x+3=9
2x=9-3
X=6/2=3
X=3
M=-1
1/y=-1
Y=-1
