Which property justifies this statement? "If 2a + 3 = b and b = 7, then 2a + 3 = 7." * A. symmetric B. transitive C. associative D. disributive

Answer: B) Transitive

The transitive property is the idea that if a = b and b = c, then a = c. Think of it as connecting a chain together. Or you can think of it in terms of moving along a map. The longer route is going from city A to city B to city C, or we can take a shortcut and go directly from city A to city C.

I believe it is associative because you can plug in 7 for be and still get the same answer as if you put in b for 7.
