Question

2 X + y = 7 write four
solution for the given equationgive ​

Answer 1

Answer:

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

Step-by-step explanation:

putting x=1

2x+y=7

=>2×1+y=7

=>2+y=7

=>y=5

so (1,5) is a solution.

putting x= -1

2x+y=7

=>2×(-1)+y=7

=> -2+y=7

=>y=9

so(-1,9) is a solution.

putting x=0

2x+y=7

=>2×0+y=7

=>y=7

so(0,7) is a solution.

putting x=2

2x+y=7

=>2×2+y=7

=>4+y=7

=>y=3

so(2,3) is a solution.
