5n + 1/8 = 1/2
so 5n = 1/2 - 1/8
so 5n = 4/8 - 1/8
so 5n = 3/8
so n = 3/(8x5)
so n = 3/40
Taking the equation to prove it
5 x 3/40 = 15/40
1/8 = 5/40
1/2 = 20/40
so 15/40 + 5/40 = 20/40
factor down
3/8 + 1/8 = 4/8 (or 1/2)

put your 1/2 on 8 its more easy so 1/2= 4/8
4/8-1/8 = 3/8
5n = 3/8
isolate your n and the answer is 3/40 or 0.075

5n=4/8-1/8
5n=3/8
n=3/8 divided by 5
n=3/40

5n+1/8=1/2 (multiply everything with 8)
40n+1=4
40n=4-1
n=3/40

1/2= 4/8 so you just subtract and get 5n=3/8 now devide by 5/1....
flip and multiply.... 3/8*1/5........n=3/40

subtract 1/8 from both sides
devide both sides by 5
this yields N = 3/8 / 5
this yields N = .075

5n=(1/2)-(1/8)
5n=3/8
n=0,075=3/40
