S=M-3
\n" ); document.write( "L=M+12
\n" ); document.write( "S+M+L=96
\n" ); document.write( "(M-3)+M+(M+12)=96
\n" ); document.write( "3M+9=96
\n" ); document.write( "3M=96-9
\n" ); document.write( "3M=87
\n" ); document.write( "M=87/3
\n" ); document.write( "M=29 ANSWER FOR THE MIDDLE SIDE.
\n" ); document.write( "S=29-3=26 FOR THE SHORT SIDE.
\n" ); document.write( "L=29+12=41 FOR THE LONG SIDE.
\n" ); document.write( "PROOF:
\n" ); document.write( "29+26+41=96
\n" ); document.write( "96=96
