QuestionIf XY=ABX Y=A B, then XYCD=ABCDX Y-C D=A B-C D Choose the property that the statement represents: Distributive Property Symmetric Property of Equality Addition Property of Equality Transitive Property of Equality Subtraction Property of Equality Reflexive Property of Equality

Studdy Solution

STEP 1

1. We are given the equation XY=AB XY = AB .
2. We need to determine which property of equality or arithmetic is represented by the statement XYCD=ABCD XY - CD = AB - CD .

STEP 2

1. Understand the given equation and the transformation.
2. Identify the property used in the transformation.

STEP 3

We start with the equation XY=AB XY = AB .

STEP 4

The transformation applied to both sides of the equation is subtracting CD CD from each side, resulting in XYCD=ABCD XY - CD = AB - CD .

STEP 5

Identify the property used: The property that allows us to subtract the same quantity from both sides of an equation without changing the equality is the Subtraction Property of Equality.
The statement represents the Subtraction Property of Equality\boxed{\text{Subtraction Property of Equality}}.
