r=2n+2w solve for n
\n" ); document.write( ".
\n" ); document.write( "First, subtract 2w from both sides:
\n" ); document.write( "r=2n+2w
\n" ); document.write( "r-2w = 2n+2w-2w
\n" ); document.write( "r-2w = 2n
\n" ); document.write( ".
\n" ); document.write( "Now, divide both sides by 2:
\n" ); document.write( "(r-2w)/2 = (2n)/2
\n" ); document.write( "(r-2w)/2 = n
\n" ); document.write( "Or,
\n" ); document.write( "r/2 - w = n\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
