15X+12(20-X)=273
\n" ); document.write( "15X+240-12X=273
\n" ); document.write( "3X=273-240
\n" ); document.write( "3X=33
\n" ); document.write( "X=11 TRIPS FOR THE 15 TON TRUCK.
\n" ); document.write( "20-11=9 TRIPS FOR THE 12 TON TRUCK.
\n" ); document.write( "PROOF
\n" ); document.write( "15*11+12*9=273
\n" ); document.write( "165+108=273
\n" ); document.write( "273=273
