Question

write the four solutions of this:
2x+y=7

Answer 1

So four solutions of the given equation are: (0, 7), ( 7/2 ,0) , (1, 5) and (3,1)

Hope it'll help you :)

Answer 2

here are the four solutions.

if x= 2
then
2(2)+y=7
4+y=7
so, y = 3

if x=3
then
2(3) +y=7
so, 6+y=7
y=1

if y= 5
so
2x+5=7
2x=2
so, x=1

if y= 3
so
2x+3=7
so 2x=4
x= 2

hope it helped you!
