To accurately identify the property that justifies Step 3 when solving an equation, I would need to know the specific equation and the actions taken in Step 3. However, I can provide a brief description of each property for context:
-
A. Reflexive Property: States that any quantity is equal to itself (e.g., \(a = a\)).
-
B. Addition Property: States that adding the same value to both sides of an equation maintains equality (e.g., if \(a = b\), then \(a + c = b + c\)).
-
C. Substitution Property: Involves replacing a variable or an expression with another equivalent value or expression (e.g., if \(a = b\), then \(b\) can replace \(a\) in any expression).
-
D. Multiplication Property: States that multiplying both sides of an equation by the same non-zero value keeps the equation balanced (e.g., if \(a = b\), then \(ac = bc\) for any \(c \neq 0\)).
If you can provide details about Step 3 or the equation you're working with, I'd be able to give a clearer answer as to which property justifies that step.
