![\[\left( 2x\text{ }-\text{ }y \right)/\text{ }\left( x\text{ }+\text{ }2y \right)\text{ }=\text{ }8/11\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-8ff8c9eb33dc424aa42c73496927a4f6_l3.png "Rendered by QuickLaTeX.com")
On cross multiplying, we get
![\[\begin{array}{*{35}{l}} 11\left( 2x\text{ }-\text{ }y \right)\text{ }=\text{ }8\left( x\text{ }+\text{ }2y \right) \\ 22x\text{ }\text{ }-11y\text{ }=\text{ }8x\text{ }+\text{ }16y \\ 14x\text{ }=\text{ }27y \\ x/y\text{ }=\text{ }27/14 \\ \end{array}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-697c24247ac52aa1afb661f6b348ee9e_l3.png "Rendered by QuickLaTeX.com")
So,
![\[7x\text{ }/\text{ }9y\text{ }=\text{ }\left( 7\text{ }x\text{ }27 \right)/\text{ }\left( 9\text{ }x\text{ }14 \right)\text{ }=\text{ }3/2\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-43bf0d338c405096a48efd0a43dfcaf9_l3.png "Rendered by QuickLaTeX.com")
If the ratio between 8 and 11 is the same as the ratio of 2x – y to x + 2y, find the value of 7x/ 9y.
