\n" ); document.write( "k-2b=5c
\n" ); document.write( "-2b=5c-k
\n" ); document.write( "b=(5c-k)/-2
\n" ); document.write( "b=-(5c-k)/2
\n" ); document.write( "b=(k-5c)/2
\n" ); document.write( ".
\n" ); document.write( "solve for c.
\n" ); document.write( "k-5c=2b
\n" ); document.write( "-5c=2b-k
\n" ); document.write( "c=(2b-k)/-5
