\n" ); document.write( "Let Tim pay:x
\n" ); document.write( "Then Bob paid:x-3
\n" ); document.write( "Together:7.80
\n" ); document.write( "(x)+(x-3)=7.80
\n" ); document.write( "2x-3=7.80

\n" ); document.write( "Bob paid: x-3=$5.40-$3.00=$2.40 (a)
\n" ); document.write( "Check, if we add what they paid do we get $7.80?
