L1890et $\"+a+\"$ = height of D. I. in feet
\n" ); document.write( "Let $\"+b+\"$ = height of K. in feet
\n" ); document.write( "---------------------------------------
\n" ); document.write( "(1) $\"+a+=+b+-+2119+\"$
\n" ); document.write( "(2) $\"+b+=+2a+%2B+229+\"$
\n" ); document.write( "-------------------------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+a+=+2a+%2B+229+-2119+\"$
\n" ); document.write( "(1) $\"+-a+=+-1890+\"$
\n" ); document.write( "(1) $\"+a+=+1890+\"$
