I hope this is it.
x=5/7 and y= - 10/3( if you meant "-6" in the first eqn) or take it as my misunderstanding. If it's +6 then,
x=1 and y=2

Given 1st Equation is 6x + 3y = 6xy --------- (1)

Given 2nd Equation is 2x + 4y = 5xy ------- (2)

Solving (1) & (2)*3, we get

6x + 12y = 15xy

6x + 3y = 6xy

----------------

        9y = 9xy

        x = 9y/9y

        x = 1.


Substitute x = 1 in (1), we get

6x + 3y = 6xy

6(1) + 3y = 6(1)y

6 + 3y = 6y

3y = 6y - 6

3y - 6y = -6

-3y = -6

y = -6/-3

y = 2.


Therefore the value of x = 1 and y = 2.


Hope this helps!
