Kendra used these steps to solve the equation 2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?
alekssr [168]
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.
