Question

If p + 9 = 25 and p = q, then q + 9 = 25.

Which property did Michaela show?
symmetric property of equality
multiplication property of equality
substitution property of equality
reflexive property of equality

Answer 1

The answer it’s 16 because when you supract 25 by 9 it’s will give you 16 and the p =q so q also 16

Answer 2

The correct answer is C) substitution property of equality.

Michaela knew that is she substituted q for p, it would still be the same equation just a different variable.

Hope this helps!
