Let $\"+n+\"$ = number of nickels
\n" ); document.write( "Let $\"+d+\"$ = number of dimes
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+n+%2B+d+=+85+\"$
\n" ); document.write( "(2) $\"+5n+%2B+10d+=+610+\"$ ( in cents )
\n" ); document.write( "---------------------
\n" ); document.write( "(2) $\"+n+%2B+2d+=+122+\"$
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( "(2) $\"+n+%2B+2d+=+122+\"$
\n" ); document.write( "(1) $\"+-n+-+d+=+-85+\"$
\n" ); document.write( " $\"+d+=+37+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+n+%2B+37+=+85+\"$
\n" ); document.write( "(1) $\"+n=+48+\"$
\n" ); document.write( "48 = number of nickels
\n" ); document.write( "37 = number of dimes
\n" ); document.write( "check:
\n" ); document.write( "(2) $\"+5n+%2B+10d+=+610+\"$
\n" ); document.write( "(2) $\"+5%2A48+%2B+10%2A37+=+610+\"$
\n" ); document.write( "(2) $\"+240+%2B+370+=+610+\"$
\n" ); document.write( "(2) $\"+610+=+610+\"$
