Write four solutions for each of the following equations:2x + y = 7

1.	Write four solutions for each of the following equations:2x + y = 7
Answer» 2x + y = 7 For x = 0, 2(0) + y = 7 ⇒ y = 7 Therefore, (0, 7) is a solution of this equation. For x = 1, 2(1) + y = 7 ⇒ y = 5 Therefore, (1, 5) is a solution of this equation. For x = −1, 2(−1) + y = 7 ⇒ y = 9 Therefore, (−1, 9) is a solution of this equation. For x = 2, 2(2) + y = 7 ⇒y = 3 Therefore, (2, 3) is a solution of this equation.

Answer»

2x + y = 7

For x = 0,

2(0) + y = 7

⇒ y = 7

Therefore, (0, 7) is a solution of this equation.

For x = 1,

2(1) + y = 7

⇒ y = 5

Therefore, (1, 5) is a solution of this equation.

For x = −1,

2(−1) + y = 7

⇒ y = 9

Therefore, (−1, 9) is a solution of this equation.

For x = 2,

2(2) + y = 7

⇒y = 3

Therefore, (2, 3) is a solution of this equation.
