Question

tell which property of equality was used.
\td - 33 = 34
\td - 33 + 33 = 34 + (30 + 3)
choose the correct answer below.
○ a. multiplication property of equality
○ b. addition property of equality
○ c. division property of equality
○ d. subtraction property of equality

Explanation:

The Addition Property of Equality states that if we add the same number to both sides of an equation, the equation remains true. In the given equation \( d - 33 = 34 \), we added 33 to the left side (\( d - 33 + 33 \)) and also added 33 (expressed as \( 30 + 3 \)) to the right side (\( 34 + (30 + 3) \)). This matches the Addition Property of Equality. The other properties (Multiplication, Division, Subtraction) involve operations other than addition, so they do not apply here.

Answer:

B. Addition Property of Equality
