Answer:
The two equations are not equivalent and no property is used.
Step-by-step explanation:
54 - (30 - 8) ... (i)
(54 - 30) - 8 ... (ii)
Solving (i) and applying PEMDAS:
We open the brackets first;
54 - 30 + 8 = 54 + 8 - 30 = 32
Solving (ii) and applying PEMDAS:
We open the brackets first;
54 - 30 = 24
24 - 8 = 16
