Thank you for the opportunity to help you with your question!

let the number of sophomores be X

juniors are = x + 6

seniors are = 3x-8

therefore

x+ x+6 + 3x-8 = 103

x+x+3x+6-8 = 103

5x -2 = 103

5x= 103 + 2

5x= 105

x= 105/5

x= 21

number of sophomores = 21

number of juniors = 21 +6 = 27

number of seniors = 3*21 -8 = 55


Please let me know if you need any clarification. I'm always happy to answer your questions.
