Question

Which property justifies the work from step 1 to step 2 below?

Step 1: -X = 15
Step 2: x= -15
a. Addition Property of =
b. Subtraction Property of =
c. Multiplication Property of =
d. Division Property of =

Answer 1

The property that justifies the work from step 1 to step 2 is the Addition Property of =.

Step-by-step explanation:

The property that justifies the work from step 1 to step 2 is the Addition Property of =. According to this property, if we add the same number to both sides of an equation, the equality still holds. So, when we add 'x' to both sides of -x = 15, we get x = 15 + x, which simplifies to x = -15.
