Given equation is:

2x+y=7

For x = - 1, we get

−2+y=7

⇒y=9

∴ (-1, 9) is a solution.

For x = 0, we get

⇒0+y=7

⇒y=7

∴ (0, 7) is a solution.

For x = 1, we get

⇒2+y=7

⇒y=5

∴ (1, 5) is a solution.

For x = 2, we get

⇒4+y=7

⇒y=3

∴ (2, 3) is a solution.

Hence, we have four solution (−1,9),(0,7),(1,5)and(2,3)

Answer 2

Given equation is:

2x + y = 7

For x = -1, we get

−2+ y = 7

⇒ y = 9

..(-1, 9) is a solution.

For x = 0, we get

⇒ 0+ y = 7

⇒ y = 7

.. (0,7) is a solution.

For x = 1, we get

⇒ 2+ y = 7

⇒ y = 5

.. (1,5) is a solution.

For x = 2, we get

⇒ 4+ y = 7

⇒ y = 3

.. (2, 3) is a solution.

Hence, we have four solution (−1, 9), (0, 7), (1,5)and(2, 3)
