The same number, -40 C.
F = 9/5 C + 32
C = 5/9 (F -32), F is -40
C = 5/9 (-40 -32)
C = 5/9 (- 72)
C = - (5 x 72) / 9
C = - 360 / 9
C = -40
In your head: "twice C minus 10% plus 32 is F"
2 x -40 C = -80; -80 - (-8) = -72; -72 +32 = -40 F
Similarly, 2x100C-20+32= 212F, boiling point of pure water at STP
