1V+6B=372 MULTIPLY BY -4 & ADD
\n" ); document.write( "4V+12B=780
\n" ); document.write( "-4A-24B=-1488
\n" ); document.write( "-------------------
\n" ); document.write( "-12B=-708
\n" ); document.write( "B=-708/-12
\n" ); document.write( "B=59 PEOPLE PER BUS.
\n" ); document.write( "1V+6*59=372
\n" ); document.write( "1V+354=372
\n" ); document.write( "1V=372-354
\n" ); document.write( "1V=18 PEOPLE PER VAN.
