On one particular day the temperature in degrees Celsius was 20° less than the temperature in Fahrenheit.
what was the temperature in degrees Fahrenheit?
:
we know that C = 5%2F9(f - 32), therefore
5%2F9(f - 32) = f - 20
Get rid of the fraction multiply both sides by 9
5(f - 32) = 9(f - 20)
distribute
5f - 160 = 9f - 180
-160 + 180 = 9f - 5f
+20 = 4f
f = 20/4
f = 5 degrees Fahrenheit
