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)
