$\"3x%2F5-2y=5\"$
\n" ); document.write( "But, $\"x=4y%2F5%2B2\"$ . So,\r
\n" ); document.write( "\n" ); document.write( " $\"3%284y%2F5%2B2%29%2F5-2y=5\"$
\n" ); document.write( " $\"%2812y%2F5%2B6%29%2F5-2y=5\"$
\n" ); document.write( " $\"5%28%2812y%2F5%2B6%29%2F5-2y%29=5%2A5\"$
\n" ); document.write( " $\"%2812y%2F5%2B6%29-10y=25\"$
\n" ); document.write( " $\"5%28%2812y%2F5%2B6%29-10y%29=5%2A25\"$
\n" ); document.write( " $\"12y%2B30-50y=125\"$
\n" ); document.write( " $\"12y-50y%2B30=125\"$
\n" ); document.write( " $\"-38y%2B30=125\"$
\n" ); document.write( " $\"-38y%2B30-30=125-30\"$
\n" ); document.write( " $\"-38y%2B0=95\"$
\n" ); document.write( " $\"-38y=95\"$
\n" ); document.write( " $\"y=-5%2F2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "again, $\"x=4%2F5y%2B2\"$ . So,\r
\n" ); document.write( "\n" ); document.write( " $\"x=4%28-5%2F2%29%2F5%2B2=-10%2F5%2B2=-2%2B2=0\"$ \r

\n" ); document.write( "\n" ); document.write( "Thus,\r
\n" ); document.write( "\n" ); document.write( " $\"x=0\"$ and $\"y=-5%2F2\"$ \r
