Assuming:
Upward → positive (+) value of ΔH
Downward → negative (-) value of ΔH
ΔHA = ΔHB + ΔHC
ΔHA = ΔHB + ΔHC
-ΔHC - ΔHC
ΔHB = ΔHA - ΔHC
Match each chemical reaction with the correct diagram according to Hess' Law
ΔHC = -ΔHA + ΔHB
ΔHB = ΔHA + ΔHC
ΔHA = ΔHB - ΔHC
ΔHB = -ΔHA - ΔHC
ΔHA = -ΔHB + ΔHC
ΔHC = ΔHA + ΔHB
ΔHB = ΔHA - ΔHC
ΔHC = -ΔHA - ΔHB
