Given the equation:
\n" ); document.write( ".
\n" ); document.write( "\"C+=+%285%2F9%29%28F+-+32%29\"
\n" ); document.write( ".
\n" ); document.write( "To solve this equation for F begin by doing the distributed multiplication on the right side.
\n" ); document.write( "By that you multiply \"5%2F9\" times each of the two terms in the parentheses. The multiplication
\n" ); document.write( "of \"%285%2F9%29\" and \"F\" results in \"%285%2F9%29%2AF\" and the multiplication of \"%285%2F9%29\" and -32
\n" ); document.write( "results in \"-%285%2F9%29%2A32\". So the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "\"C+=+%285%2F9%29%2AF+-+%285%2F9%29%2A32\"
\n" ); document.write( ".
\n" ); document.write( "Get rid of the \"-%285%2F9%29%2A32\" on the right side by adding \"%2B%285%2F9%29%2A32\" to both sides. This
\n" ); document.write( "addition cancels the \"-%285%2F9%29%2A32\" on the right side. And after the addition to the left side
\n" ); document.write( "the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "\"C+%2B+%285%2F9%29%2A32+=+%285%2F9%29%2AF\"
\n" ); document.write( ".
\n" ); document.write( "Next multiply both sides (all terms) by \"9%2F5\" to get rid of the fractions. This multiplication
\n" ); document.write( "of all terms results in:
\n" ); document.write( ".
\n" ); document.write( "\"%289%2F5%29%2AC+%2B+%289%2F5%29%2A%285%2F9%29%2A32+=+%289%2F5%29%2A%285%2F9%29%2AF\"
\n" ); document.write( ".
\n" ); document.write( "Notice that when you multiply \"9%2F5\" times \"5%2F9\" the result is \"1\". This makes
\n" ); document.write( "the equation become:
\n" ); document.write( ".
\n" ); document.write( "\"%289%2F5%29%2AC+%2B+1%2A32+=+1%2AF\"
\n" ); document.write( ".
\n" ); document.write( "which multiplies out to give:
\n" ); document.write( ".
\n" ); document.write( "\"%289%2F5%29%2AC+%2B+32+=+F\"
\n" ); document.write( ".
\n" ); document.write( "And reversing the sides this is:
\n" ); document.write( ".
\n" ); document.write( "\"F+=+%289%2F5%29%2AC+%2B+32\"
\n" ); document.write( ".
\n" ); document.write( "This is the answer to your problem. Hope that it helps you to understand the problem a
\n" ); document.write( "little better.
