Which of the following is an example of a valid use of the multiplication property of equality? a. to isolate s in the equation s – 4 = –12, divide both sides of the equation by b. to isolate s in the equation s – 4 = –12, multiply both sides of the equation by c. to isolate s in the equation –4s = –12, divide both sides of the equation by d. to isolate s in the equation –4s = –12, multiply both sides of the equation by

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.

Step-by-step explanation:

We have a set of an example of equations; we need to study the use of multiplication property of equality.

A. to isolate s in the equation s – 4 = –12, divide both sides of the equation by.In this sentence, to isolate s we do not need multiplication only addition and subtraction.

B. to isolate s in the equation s – 4 = –12, multiply both sides of the equation by. In this sentence, to isolate s we do not need multiplication only addition and subtraction.

C. to isolate s in the equation –4s = –12, divide both sides of the equation by -4. This sentence is correct, and it uses division. However, we are studying multiplication property not division.

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1. Firstly, it is a good idea to change both negative signs to positive by multiplying by -1 to isolate s.

Finally, we can conclude that a valid use of the multiplication property of equality is D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.
