you can't.
The thing is x and y are variables so you can put any number in their place due to which the equations may satisfy for some cases while it won't for others.
The value of x and y can be found though

wrong answer
really?? I would say wrong question
U solved it taking the equations as a pair of linear equations
*I*
taking as two seperate equations u will have infinite solutions
but one can't prove it. I am sorry

Step-by-step explanation:
a1 = 1 ,a2=3
b1 = -3 , b2 =9
c1 = -3, c2 = -2
so by applying the the formula
a1/a2=1/3=b1/b2=-3/-9=c1/c2=-3/-2
=) 1/3=1/3but no equal to 3/2
SO, a1/a2=b1/b2 but not equal to c1/c2
therefore they are inconsistent,parallel lines
