Step-by-step explanation:

our equation are

2x+3y=9

2x = 9-3y

x = 9-3/2

2

putting the value x in (2)

4x+6y=18

9-3y

4. 2. + 6y = 18

2 (9-3y) + 6y = 18

18 - 6y + 6y = 18

18=18

it is true for all values of x and y

since the given equation has infinitely many solutions,

that is why we cannot obtain a unique solution
