Let x=shorter piece
\n" ); document.write( "Then x+4=longer piece\r
\n" ); document.write( "\n" ); document.write( "Now we are told that:
\n" ); document.write( "x+x+4=18 subtract 4 from both sides\r
\n" ); document.write( "\n" ); document.write( "x+x+4-4=18-4 collect like terms\r
\n" ); document.write( "\n" ); document.write( "2x=14 divide both sides by 2\r
\n" ); document.write( "\n" ); document.write( "x=7 ft------------------shorter piece\r
\n" ); document.write( "\n" ); document.write( "x+4=7+4=11 ft -------------longer piece\r
\n" ); document.write( "\n" ); document.write( "CK\r
\n" ); document.write( "\n" ); document.write( "7+11=18
\n" ); document.write( "18=18
\n" ); document.write( "also
\n" ); document.write( "7+4=11
\n" ); document.write( "11=11\r
