$\"I=nE%2F%28nr%2BR%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"I%28nr%2BR%29=nE\"$ multiplied both sides by (nr+R)
\n" ); document.write( ":
\n" ); document.write( " $\"Inr%2BIR=nE\"$ distributed left side
\n" ); document.write( ":
\n" ); document.write( " $\"IR=nE-Inr\"$ subtracted Inr from both sides
\n" ); document.write( ":
\n" ); document.write( " $\"IR=n%28E-Ir%29\"$ factored out n on right side
\n" ); document.write( ":
\n" ); document.write( " $\"n=IR%2F%28E-Ir%29\"$ divided both sides by (E-Ir)
\n" ); document.write( " \n" ); document.write( "

\n" );
