Question :-

Solve for x and y :-

\rm \frac{2}{x} + \frac{2}{3y} = \frac{1}{6}

\rm \frac{3}{x} + \frac{2}{y} = 0

Answer :-

Let,

\rm \frac{1}{x} = u

\rm \frac{1}{y} = v

Substituting in equation -

\rm 2u + \frac{2}{3}v = \frac{1}{6} - ➀

\rm 3u + 2y = 0 - ➁

Multiplying the equation ➀ by 3

and equation ➁ by 2

Equation ➀ -

\rm 3 ( 2u + \frac{2}{3}v = \frac{1}{6} )

\rm 6u + 2v = \frac{1}{2} - ➂

Equation ➁ -

\rm 2 ( 3u + 2y ) = 0

\rm 6u + 4v = 0 - ➃

Subtracting the equation ➂ from ➃

\rm 6u + 4v - 6u - 2v = 0 - \frac{1}{2}

\rm 2v = - \frac{1}{2}

\rm v = - \frac{1}{4}

Substituting the value of v in equation ➀

\rm 2u + \frac{2}{3}v = \frac{1}{6}

\rm 2u + \frac{2}{3} \times \frac{-1}{4}= \frac{1}{6}

\rm 2u + \frac{-1}{6}v = \frac{1}{6}

\rm 2u = \frac{1}{6} + \frac{1}{6}

\rm u = \frac{1}{6}

\rm x = \frac{1}{u}

\boxed{\rm x = 6 }

\rm y = \frac{1}{v}

\boxed{\rm y = -4 }
