Question

The​ world's largest university​ (by enrollment) is University​ A, followed by University B. If the enrollment in University A is 3.5 million more students than University B and their combined enrollment is 9.5 million​ students, find the enrollment for each university?

Answer 1

Let x be the number of people at University B

x + (x+3.5) = 9.5
2x +3.5 = 9.5
2x = 6
x = 3 million students at University B

x + 3.5 = 3 + 3.5 = 6.5 million students at University A
