Question

Solve 4x+9y = 30xy;5y-3x = xy

Answer 1

Step-by-step explanation:

: 4x + 9y = 30xy

: 4x + 9y = 30(5y - 3x) (Since xy = 5y - 3x)

: 150y - 90x = 4x + 9y

: 141y = 94x

: (x/y) = 141/94 = 3/2

Since, the ratio of x and y respectively is 3:2 that means x = 3k and y = 2k (k = any rational number)

So, on the basis of above description we can say :

y = 2,4,-2, 0,-4, etc

x = 3,6,-3, 0,-6, etc
