Adding 6 to numerator of a fraction , the numerator becomes twice the denominator. The quadratic equation satisfying the statement is
both (a) and (b)
Let numerator of the fraction be x and denominator be y .
Adding 6 to numerator (x+6) , the numerator becomes twice the denominator (x+6 = 2y)
Now if we consider y as numerator and x as denominator , we get (y+6 = 2x)
