If 4x - 12 > x + 9, which of the following must be true?
(A) x > 6 (B) x < 7 (C) x > 7 (D )x > 8 (E )x < 8
x => 7
Why (A) is the right answer (the question does not specify that x is an integer)? Although (A) is the only answer that can cover all the values from the original inequality, but if x=6.3 it does not satisfy the question.
Please, explain, how to follow GMAT logic here.
Thank you
