(3n + 15) / 2
5 hours subtracted from 7 hours is 2 hours. 5 minutes subtracted from 20 minutes is 15 minutes.Therefore, the answer is 2 hours 15 minutes
If you mean (2/5 times 30) minus (4/3 times 15/8) then the answer is 19/2 or 9.5

(4 times 3) plus 2 plus 1
15 x (8/4) + 2 = 15 x 2 + 2 = 32
7 + (2 x 15) - 6 = 31
32 - (15 x 2) + 3 = 5
