You can put this solution on YOUR website!
Let $\"+b+\"$ = number of bicycles
\n" ); document.write( "Let $\"+t+\"$ = number of tricycles
\n" ); document.write( "Both types have 1 seat each, so
\n" ); document.write( "(1) $\"+b+%2B+t+=+24+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+2b+%2B+3t+=+61+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "Multiply both sides of (1) by $\"+2+\"$
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) $\"+2b+%2B+3t+=+61+\"$
\n" ); document.write( "(1) $\"+-2b+-+2t+=+-48+\"$
\n" ); document.write( " $\"+t+=+13+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+b+%2B+t+=+24+\"$
\n" ); document.write( "(1) $\"+b+%2B+13+=+24+\"$
\n" ); document.write( "(1) $\"+b+=+11+\"$
\n" ); document.write( "There are 11 bicycles and 13 tricycles
\n" ); document.write( "check answer:
\n" ); document.write( "(2) $\"+2b+%2B+3t+=+61+\"$
\n" ); document.write( "(2) $\"+2%2A11+%2B+3%2A13+=+61+\"$
\n" ); document.write( "(2) $\"+22+%2B+39+=+61+\"$
\n" ); document.write( "(2) $\"+61+=+61+\"$
\n" ); document.write( "OK
