Let $\"d\"$ = number of dimes
\n" ); document.write( "Let $\"q\"$ = number of quarters
\n" ); document.write( "(1) $\"d+%2B+q+=+450\"$
\n" ); document.write( "(2) $\"10d+%2B+25q+=+7500\"$ (in cents)
\n" ); document.write( "multiply both sides of (1) by $\"10\"$
\n" ); document.write( "and subtract from (2), find $\"q\"$ , then
\n" ); document.write( "find $\"d\"$ \n" ); document.write( "

\n" );
