Answer:

-
(61)/(11)

Explanation:


(x)/(y) =
(5)/(6) ( cross- multiply )

6x = 5y ( divide both sides by 6 )

x =
(5)/(6) y

Then


(5x+6y)/(5x-6y) ← substitute x =
(5)/(6) y into the expression

=
((25)/(6)y+6y )/((25)/(6)y-6y )

=
((61)/(6)y )/(-(11)/(6)y )

=
((61)/(6) )/(-(11)/(6) )

=
(61)/(6) × -
(6)/(11)

= -
(61)/(11)
