(−4.5 + 4.2 + 5.6 − 7.3 Original problem)
(1−4.5 + 4.2 + 5.6 + (−7.3) Additive inverse)
(2−4.5 + (−7.3) + 4.2 + 5.6 Commutative property)
(3(−4.5 + (−7.3)) + (4.2 + 5.6) Associative property)
(4−11.8 + 9.8 Simplify)
(5−21.6 Simplify)
Thanks For the Help In advance

heres what i done
−4.5 + 4.2 + 5.6 − 7.3
−4.5 + 4.2 + 5.6 + (−7.3)
−4.5 + (−7.3) + 4.2 + 5.6
(−4.5 + (−7.3)) + (4.2 + 5.6)
-11.8+9.8 = -2
The red is incorrect up top and corrected below

+1009 Thanks so instead of Having the two you put in red that you said were wrong have the one you said was correct instead of the two were wrong
so basically what I am saying is put the red one that you said was the correct answer in the spot were you said the two in red were the problem.
