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!
