Given:
y − 3x > 12
−y + x > 38 [aside: I rearranged the x and y so that they're in the same format as the equation above]

IMPORTANT: Since the inequality symbols are facing the SAME DIRECTION, we can ADD the two inequalities.
We get: -2x > 50
Divide both sides by -2 to get: x < -25 [aside: since we divided by a NEGATIVE value, we REVERSE the inequality symbol]

So, x can be ANY value that's less than -25

Answer: A and B
