Welder A -> 3x
\n" ); document.write( "Welder B -> x
\n" ); document.write( "Total Time -> 3 hours\r
\n" ); document.write( "\n" ); document.write( "The equation would be:\r
\n" ); document.write( "\n" ); document.write( "\"3x%2Bx=3\"
\n" ); document.write( "\"4x=3\"
\n" ); document.write( "\"x=3%2F4\"\r
\n" ); document.write( "\n" ); document.write( "Welder A -> 3x
\n" ); document.write( "\"3%2A%283%2F4%29\"
\n" ); document.write( "\"9%2F4+hours\" or 2.25hours
\n" ); document.write( "
