Kevin, I already answered this problem,

\n" ); document.write( "Oops! My error, I did not see the subscript of 2.
\n" ); document.write( "Let's try again.
\n" ); document.write( " $\"1%2FR+=+1%2FR%5B1%5D+%2B+1%2FR%5B2%5D\"$
\n" ); document.write( "Solve for $\"R%5B2%5D\"$ :
\n" ); document.write( " $\"1%2FR+=+1%2FR%5B1%5D%2B1%2FR%5B2%5D\"$ } Subtract $\"1%2FR%5B1%5D\"$ from both sides.
\n" ); document.write( " $\"1%2FR+-+1%2FR%5B1%5D+=+1%2FR%5B2%5D\"$ Simplify the left side.
\n" ); document.write( " $\"%28R%5B1%5D-R%29%2F%28R%2AR%5B1%5D%29+=+1%2FR%5B2%5D\"$ Invert both sides.
\n" ); document.write( " $\"R%2AR%5B1%5D%2F%28R%5B1%5D-R%29+=+R%5B2%5D\"$
\n" ); document.write( " $\"highlight%28R%5B2%5D+=+R%2AR%5B1%5D%2F%28R%5B1%5D-R%29%29\"$ \n" ); document.write( "

\n" );
