Let Sam have $x initially
\n" ); document.write( "==>
\n" ); document.write( "Mark has $(x-6)
\n" ); document.write( "and
\n" ); document.write( "Dean has $(x-12)
\n" ); document.write( "As the total amount is $75
\n" ); document.write( "x+(x-6)+(x-12)=75
\n" ); document.write( "==> 3x-6-12=75
\n" ); document.write( "==> 3x-18=75
\n" ); document.write( "Adding 18 on both sides,
\n" ); document.write( "==> 3x-18+18=75+18
\n" ); document.write( "==> 3x=93
\n" ); document.write( "==> 3x/3=93/3
\n" ); document.write( "==> x=31
\n" ); document.write( "==> Sam has $31
\n" ); document.write( "
\n" );
