Question

Kendra used these steps to solve the equation 2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?

A.All values of x make the equation true

B.No values of x make the equation true.

C.The solution is x = 5.

D.The result is not correct because Step 2 has an error.

Answer 1

The answer is A.
 If a redundant conclusion is reached in basic algebra this states that the variable holds all possible real values. 
If you algebraically solve Kendra's you do achieve the true statement 5 = 5 (leaving out D). And if you test any value of x for the equation it does hold true (getting rid of B). 
Hopefully this makes sense.

Answer 2

The answer is A because it makes the equation true and the other ones does not make sense
