Question

Uma wrote the following. 15=x x=15 Which property of equality did she use?

Answer 1

Answer:

The answer is - symmetric property of equality

Step-by-step explanation:

Uma wrote the following.

15=x; x=15

Transitive property of equality states that if a = b and b = c, then a = c. So, this is not the answer.

Substitution property of equality states that if x = y, then x can be substituted in for y and y can be substituted for x in any equation. This is not the answer.

Multiplication property of equality states that if you multiply both sides of an equation by the same number, the sides remain equal. So, this is not the answer.

Symmetric property of equality states that if a = b then b = a. So, this is the answer.

Answer 2

That would be the symmetric property of equality
