Which properties of equality justify steps c and f A. Subtraction property of equality; multiplication property of equality B. Multiplication property of equality; Division property of equality C. Addition property of equality; Subtraction property of equality D. Addition property of equality; Division property of equality

Option D. Addition property of equality; Division property of equality

Explanation:

a + c = c + a which we have as that in step C is being given as 23 + 11 = -11 +(-4x) + 11

We added 11 to both side of the equation In step C so that we can eliminate 11 in the right side of the equation.

This signifies the property which is known as

Addition property of equality.

Whereby, In step 'f' and to be able to eliminate 4 in the equation, In this step equation we divided both sides of the equation by -4 to eliminate 4 in fraction.

What we have just did above is known as the division property.

For this reason, the correct answer is D.
