\n" ); document.write( "\n" ); document.write( "let two-digit number be $\"xy\"$ where $\"x=tens\"$ and $\"y=ones\"$ \r
\n" ); document.write( "\n" ); document.write( "given:\r
\n" ); document.write( "\n" ); document.write( " $\"y=x%2B3\"$ .....1\r
\n" ); document.write( "\n" ); document.write( " $\"x%2By=13\"$ ....2\r
\n" ); document.write( "\n" ); document.write( "substitute $\"y\"$ from 1\r
\n" ); document.write( "\n" ); document.write( " $\"x%2Bx%2B3=13\"$ ...solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x=13-3\"$ \r
