Question 4 • (OC27) MATH COLL ALGEBRA-1200710-S1-Degele-VOL7006P
Divide both sides of −4|−2x + 6| = −24 by −4 to get |−2x + 6| = 6. The expression inside the absolute value can equal 6 or −6: solving −2x + 6 = 6 gives x = 0, and solving −2x + 6 = −6 gives x = 6. So the solution is x = 0 or x = 6, choice C.
