Question

Write four solutions for the following equation:- 2x + y = 7

Solution

2x + y = 7

For x = 0,

2(0) + = 7

⇒ = 7

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

For = 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 = 2,

2(2) + y = 7

y = 3

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

  Is there an error in this question or solution?
