equity=unknown

debt can be  derived using the debt ratio as shown thus:

debt ratio=debt/total assets

debt ratio=40%

debt=unknown

total assets=$4 million

40%=debt/$ 4 million

debt=40%*$4 million

debt=$1.6 million

$4 million=equity+$1.6 million

equity=$4 million-$1.6 million

equity =$2.4 million
