To solve the first equation, you can start by multiplying both sides of the equation by (15-y/8) to get rid of the fraction:

35 = 5*(15-y/8)
35 = 75 - 5y/8

Now, move the terms around to isolate y:

5y/8 = 75 - 35
5y/8 = 40
y = (40*8)/5
y = 64

So, y = 64

To solve the second equation:

32 - 16/n = 30
Add 16/n to both sides:

32 = 30 + 16/n
Subtract 30 from both sides:

2 = 16/n
Multiply both sides by n:

2n = 16
Divide by 2:

n = 16/2
n = 8

So, the solution to the second equation is n = 8.
