2x+y=7for x=0,

2×0 + y = 7

⇒ 0 + y = 7

⇒ y = 7

So (0,7) is a solution.

for x=1,

2×1 + y = 7

⇒ 2 + y = 7

⇒ y = 7-2 = 5

So (1,5) is a solution.

for x=2,

2×2 + y = 7

⇒ 4 + y = 7

⇒ y = 7-4 = 3

So (2,3) is a solution.

for x=3,

2×3 + y = 7

⇒ 6 + y = 7

⇒ y = 7-6 = 1

So (3,1) is a solution.

Four solutions are :(0,7), (1,5), (2,3) and (3,1).

2x+y=7

y = 7-2x

putting different values of x,will get corresponding value of y.

1. x =0

y = 7-2(0)

y =5

2. x = 1

y = 7-2(1)

y = 5

3. x = 2

y = 7-2(2)

y =3

4. x=4

y = 7- 2(4)

y = -1

so the four solutions are (0,7) , (1,5) , (2,3) , (4, -1)

y = 7-2x

putting different values of x,will get corresponding value of y.

1. x =0

y = 7-2(0)

y =5

2. x = 1

y = 7-2(1)

y = 5

3. x = 2

y = 7-2(2)

y =3

4. x=4

y = 7- 2(4)

y = -1

so the four solutions are (0,7) , (1,5) , (2,3) , (4, -1)
