2 credit hours

Explanation:

Given

14x + 16y = 74

Required

Determine the number of credit hours y greater than x

From the question, we understand that

y => spring semesters

x => fall semesters

From the equation,

14 represent the number of credit hours in each fall semester

16 represent the number of credit hours in each spring semester

Calculate the difference.

Difference = 16 hours - 14 hours

Difference = 2 hours

Hence, the student take 2 more hours in each spring semester than in each fall semester
