Answer:
Division Property of Equality
Step-by-step explanation:
Addition Property of Equality :
a = b ⇒ a + c = b + c
Subtraction Property of Equality
a = b ⇒ a - c = b - c
Multiplication Property of Equality :
a = b ⇒ ca = cb,
Division Property of Equality :
,
Here, the given equation is,
0.36x=-1.8,
For finding the value of x we need to isolate x,
For this we must divide both sides by 0.36,
That is, we were applied 'Division Property of Equality'.
