9x - 4y = 6xy be second equation

use elemination method to find the values of x and y

11x - 7 y = xy multiply this equation by 6 we get

66x - 42 y = 6xy

now come to the other equation

9x - 4y = 6xy multiply this equation by 1 for making the xy same we get

9x - 4y = 6xy

use these equation and subtract it

66x - 42y = 6xy

9x - 4y =6 xy

- + -

57x - 38y = 0

57 x = 38 y

x= 38y /57

substitute this equation in equation second

9x - 4y = 6xy

9*38y/57 - 4y = 6*38y²/57

now divide this equation by y to get the y equal in all

9*38/57 - 4 = 6*38y/57

342 - 228 = 6×38y

114=6*38y

57 =3*38 y

y=29/38

but this value in equation 57x = 38 y

57x = 38*57/38 *3

57x =57/3

x=1/3

by this we get the value of x and y

y=29/38 ,x=1/3
