Answer:
Infinite solutions
Step-by-step explanation:
2x+3y=9
=> x = (9-3y)/2
Substitute this value in the other equation.
=> 4x+6y=18
=> 4(9-3y)/2+6y=18
=> 18-6y+6y=18
=> 18=18
This shows that there are infinite number of solutions for the given pair of equations.

Answer:
2x+3y=9.....(1)
4x+6y=18.....(2)
eq (1) can be written as
2x=9-3y
x=9-3y/2...(3)
substitute value of x from eq 3 in eq 2 we get
4(9-3y)/2+6y=18
2(9-3y) +6y =18
18-6y+6y=18
18=18
therefore equation has infinite no. of solution
