Solve the rational-coefficient system of equations for the ordered pair
(
x
,
y
)
(x, y)
(

)
:

x
y
=

x
y
=

\begin{cases} \frac{8x + 2y}{xy} = 4 \\ \frac{17x + 5y}{xy} = 16 \end{cases}

Hint: Rewrite each equation by splitting the fraction. Then let
u
=
1
x
u = \frac{1}{x}
u
=
x
1
and
v
=
1
y
v = \frac{1}{y}
v
=
y
1
