\n" ); document.write( "\n" ); document.write( "Let represent the number of bicycles and let represent the number of tricycles. Then the number of bicycle wheels is and the number of tricycle wheels is .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Using what we know:\r

\n" ); document.write( "\n" ); document.write( "Solve the system. Substitution is probably the easiest method for this problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Actually, you can save a step by changing the setup a little.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let represent the number of bicycles as before. But since we know that there are 15 cycles altogether, we can say the number of tricycles is . That means the number of bicycle wheels is again , but the number of tricycle wheels is \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now all you need is one equation:\r
