\n" ); document.write( "Equations:
\n" ); document.write( "k - e = 20 cm
\n" ); document.write( "8k = 9e
\n" ); document.write( "----
\n" ); document.write( "Substitute for \"k\" and solve for \"e\":
\n" ); document.write( "k = 20+e
\n" ); document.write( "---
\n" ); document.write( "8(20+e) = 9e
\n" ); document.write( "160 + 8e = 9e
\n" ); document.write( "e = 160 cm (Elane's height)
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"k\":
\n" ); document.write( "k = 20 + e
\n" ); document.write( "k = 180 cm (Kaari's height)
