Hi,
Any admin/mod could please fix the typos in this question? Bunuel
There are actually 2 correct answers (A) and (C)
Which of the following equations is NOT equivalent to 4a^2 = 16b^2 + 49?
(A) 16b^2+49/4= a^2
(C) 2a-4b=7
Based on the posted OA as (C), adjustment should be made on (A) as follows: (A) 4b^2+49/4= a^2, so that (A) would become equivalent to 4a^2 = 16b^2 + 49
Please fix it so that users will not be confused.. Thanks.
