Givn: $\"%281%2Fr%29=+%281%2Fs%29+%2B+%281%2Ft%29\"$
\n" ); document.write( "The first thing I would do is get the part with s in it by itself.
\n" ); document.write( "This can be done by subtracting 1/t from both sides.
\n" ); document.write( " $\"%281%2Fr%29+-+%281%2Ft%29+=+1%2Fs\"$
\n" ); document.write( "Now multiply both sides by s
\n" ); document.write( " $\"s%2A%28%281%2Fr%29-%281%2Ft%29%29+=+1\"$
\n" ); document.write( "Then divide both sides by [(1/r)-(1/t)]
\n" ); document.write( " $\"s+=+1%2F%28%281%2Fr%29-%281%2Ft%29%29\"$ \n" ); document.write( "

\n" );
