Question

Write the four solutions of the equation 2x + y =3

Answer 1

Answer:

x = 1 , y = 2 .... x= 2 ,y = -1

Answer 2

Answer:

Step-by-step explanation:

a)2x + y = 3......(1)

On putting x=0 in equation 1

2x+y=3

2×0+y=3

0+y=3

Y=3

So( 0, 3) is a solution of given equation.

let y=0

2x+y=3

2x+0=3

2x=3

X= 3/2

So(3/2,0) is a solution of given equation.

let x = 1

2x+y=3

2×1+y=3

2+y=3

Y= 3-2

Y=1

(1,1) is the solution.

let x = 2

2x+y=3

2×2+y=3

4+y=3

Y= 4-3

Y= 1

The solution is (2,1)

Hence, 4 out of the infinitely many solutions of the given equation are(0,3), (3/2,0),(1,1),(2,1)
