\n" ); document.write( "Let $\"x\"$ = one number
\n" ); document.write( " $\"y\"$ = the other number
\n" ); document.write( "1st condition: $\"highlight%28x%29=3y\"$
\n" ); document.write( "2nd condition: $\"highlight%28x%29-y=13\"$
\n" ); document.write( "Substitute highlighted becomes:
\n" ); document.write( " $\"3y-y=13\"$
\n" ); document.write( " $\"2y=13\"$ -------> $\"cross%282%29y%2Fcross%282%29=cross%2813%296.5%2Fcross%282%29\"$
\n" ); document.write( " $\"highlight%28y=6.5%29\"$ , the other number
\n" ); document.write( " $\"x=3%2A6.5=highlight%2819.5%29\"$ , the number
\n" ); document.write( "Let's check via 2nd condition:
\n" ); document.write( "The difference is 13:
\n" ); document.write( " $\"19.5-6.5=13\"$
\n" ); document.write( " $\"13=13\"$
