Five years ago,
\n" ); document.write( " $\"K-5=3%28D-5%29\"$
\n" ); document.write( " $\"K-5=3D-15\"$
\n" ); document.write( "1. $\"K-3D=-10\"$
\n" ); document.write( "Five years from now,
\n" ); document.write( " $\"K%2B5=2%28D%2B5%29\"$
\n" ); document.write( " $\"K%2B5=2D%2B10\"$
\n" ); document.write( "2. $\"K-2D=5\"$
\n" ); document.write( "Subtract 2 from 1,
\n" ); document.write( " $\"K-3D-K%2B2D=-10-5\"$
\n" ); document.write( " $\"-D=-15\"$
\n" ); document.write( " $\"D=15\"$
\n" ); document.write( "Now use either equation to solve for K.\r
