2/5 x + 3/2 y = 2\r
\n" ); document.write( "\n" ); document.write( "7/3 x - 5/4 y = -5\r
\n" ); document.write( "\n" ); document.write( "Multiply the first equation by 10. i.e both sides.\r
\n" ); document.write( "\n" ); document.write( "4x + 15y = 20\r
\n" ); document.write( "\n" ); document.write( "Multiply the first equation by 12.\r
\n" ); document.write( "\n" ); document.write( "28x - 15y = -60\r
\n" ); document.write( "\n" ); document.write( "add the 2 equations\r
\n" ); document.write( "\n" ); document.write( "32x = -40\r
\n" ); document.write( "\n" ); document.write( "x = -1.25 or -5/4\r
\n" ); document.write( "\n" ); document.write( "y = 5/3
\n" ); document.write( "
\n" );
