Question

find two pairs of solution of the equation 2x + y =7
​

Answer 1

Answer:

Hi

Explanation:

The given equation is 2x+y=7    ... (1)  

Putting x=0 in (1), we get,

2×0+y=7

⇒x=  2 7

​  ∴(  2 7  ,0) is a solution of (1).

Further, putting y=1 in (1), we get  

2x+1=7

⇒2x=7−1

⇒2x=6

⇒x=3

∴(3,1) is a solution of (1).

Hence, (0,7);(  27 ,0) and (3,1) are three solutions of the given equation.
