Step-by-step explanation:
for x = 1
2(1)+3y=7
3y=7-2=5
y=5/3
Sol. = (2,5/3)
for x = 2
2(2)+3y=7
3y=7-4=3
y=3/3=1
Sol. is (2,1)
for y=2
2x+3(2)=7
2x=7-6=1
x=1/2
Sol. is (1/2,2)
For x =3
2(3)+3y=7
3y=7-6=1
y=1/3
Sol. is (3,1/3)

take x=1
2×1 +3y=7
2+3y=7
3y=5
y=5/3
so one solution is x =1and y=5/3
take x=2
therefore 2×2+3y = 7
4+3y =7
3y=3
y=1
so second solution is x =2, y=1
take x=3
2*3+3y =7
6+3y=7
3y=7-6
y=1/3
so third solution is x=3,y=1/3
take x=4
2*4+3y=7
8+3y=7
3y=7-8
y= -1/3
hence the fourth solution is x=4 , y = -1/3
