Sample Problem
Let ◻ be defined as a◻b = 2a + 4b, where a and b are nonzero numbers. If 3 ◻ x = 16, what is the value of x?
Answer Options
(A) 2
(B) 5/2
(C) 11/4
(D) 13/14
(E) 9/2
View Correct Answer
(B) 5/2
If 3 ◻ x = 16, then 2(3) + 4x = 16. Solving this equation yields 4x = 10 or x = 10/4, which reduces to 5/2.
