\n" ); document.write( "------------
\n" ); document.write( "The equation is \"solved\" for F.
\n" ); document.write( "-40 degrees is the temp where the F and C degrees are equal.
\n" ); document.write( "----
\n" ); document.write( "Find the temp where Fahrenheit and Celsius are equal.
\n" ); document.write( "---
\n" ); document.write( "F = (9/5)C + 32
\n" ); document.write( "F = C
\n" ); document.write( "----
\n" ); document.write( "F = (9/5)F + 32
\n" ); document.write( "(-4/5)F = 32
\n" ); document.write( "F = 32/(-4/5) = 32*(-5/4) = -40 degrees
\n" ); document.write( "
\n" );
