$\"+275+%2F+1575+=+950+%2F+R+\"$
\n" ); document.write( "Divide top and bottom of left side by $\"+25+\"$
\n" ); document.write( " $\"+11%2F63+=+950%2FR+\"$
\n" ); document.write( "Multiply both sides by $\"+63R+\"$
\n" ); document.write( " $\"+11R+=+950%2A63+\"$
\n" ); document.write( " $\"+11R+=+59850+\"$
\n" ); document.write( " $\"+R+=+5440.91+\"$ ohms \n" ); document.write( "
