```							hello karthik, the given eqns are:3x – 5y=20......(a)6x – 10y=40.....(b)now if we multiply (a) on both sides by 2, we get2*(3x – 5y)= 2*20or 6x – 10y= 40, which is precisely the same as (b). hence, (a) and (b) are equivalent to each other.hence there are infintely many solutions, such as (0, – 4); (5, – 1); (10, 2) etc.kindly approve :=)
