Given information:\r
\n" ); document.write( "\n" ); document.write( "x= smaller number\r
\n" ); document.write( "\n" ); document.write( "y= larger number\r
\n" ); document.write( "\n" ); document.write( "y-x=15\r
\n" ); document.write( "\n" ); document.write( "therefore y= x+15
\n" ); document.write( "
\r
\n" ); document.write( "\n" ); document.write( "4x + 2y = 120
\n" ); document.write( "4x + 2(x+15) = 120
\n" ); document.write( "4x + 2x + 30 = 120
\n" ); document.write( "6x + 30 = 120
\n" ); document.write( "6x = 90
\n" ); document.write( "x= 15\r
\n" ); document.write( "\n" ); document.write( "therefore
\n" ); document.write( "

\n" ); document.write( "x = 15
\n" ); document.write( "y = 30
\n" ); document.write( "
\n" );
