If the larger number is n, then the smaller is n - 12. $\"%28n-12%29%2B2n=39\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28n-12%29%2B2n=39\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"3n-12=39\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"3n=39%2B12=51\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"n=17\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check: if the larger is 17, the smaller must be 17 - 12 = 5. Twice the larger is 34 plus 5 is 39 -- checks.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
