Find all pairs (N, X) of integers such that:

Xo Celsius = N*Xo Fahrenheit

*** C = 5(F-32)/9, where C and F respectively denotes Celsius and Fahrenheit scales of temperature.

-40°C = -40°F; multiple is 1
-20°C = -4°F; multiple is 5
-18°C = -.4°F; multiple is 45
-16°C =  3.2°F; multiple is-5
-15°C =  5°F; multiple is -3

The pairs of integers are (1,-40), (5,-20), (45,-18), (-5,-16), (-3,-15)

The Fahrenheit temperatures need not be integers, only the Celsius.

Text1.Text = Text1.Text & " done"
