If you started with:
\n" ); document.write( " $\"Z=%28Rr%29%2F%28R%2Br%29\"$
\n" ); document.write( "Multiply both sides by (R+r):
\n" ); document.write( " $\"Z%28R%2Br%29=Rr\"$
\n" ); document.write( " $\"ZR%2BZr=Rr\"$
\n" ); document.write( " $\"Zr=Rr-ZR\"$
\n" ); document.write( " $\"Zr=R%28r-Z%29\"$
\n" ); document.write( " $\"%28Zr%29%2F%28r-Z%29=R\"$
\n" ); document.write( " \n" ); document.write( "
