\"A store owener sells two pairs of running shoes for each pair of high tops\" ___ r = 2h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"He plans to order 144 pairs of shoes\" ___ r + h = 144\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "two unknowns (r and h) and two equations\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ (2h) + h = 144 ___ h = 48\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ r = 2(48) = 96
\n" ); document.write( "
\n" );
