multiply both sides by 8 to get rid of denominators
6n + 128 = 16 - 1n
add 1 n to each side
7n = -112
divide by 7 both sides
n = - 16

3/4n+16=2-1/8N
First--get all the Ns on the same side:
3/4n+16-16=2-1/8n-16
3/4n=-14-1/8n
3/4n+1/8n=-14-1/8+1/8n
3/4 is the same as 6/8
6/8n+1/8n=-14
7/8n=-14
Multiply by 8 on both sides to get rid of the fraction
7/8n*8=-14*8
7n=-112
solve for n
n=-16
Check
Plug in -16 for n to see if it works.

Multiply both sides by 8 to get rid of the fractions:
8(3/4n+16)=8(2-1/8n)
6n+128=16-n
Add n to both sides:
7n+128=16
Subtract 128 to both sides:
7n=-112
n=-16
Check:
3/4(-16)+16=2-1/8(-16)
-12+16=2+2
4=4

Subtract 16 from both sides:
3/4n = 2 - 1/8n - 16
3/4n = - 1/8n - 14
Add -1/8n to both sides:
3/4n + 1/8n = -14
Convert to common denominator for the left:
6/8n + 1/8n = -14
7/8n = -14
Multiply by 8n on both sides:
7 = -112n
n = 7/-112 = -0.0625
Hope this helps :)

3/4n = 6/8n (duh)
6/8n + 1/8n = 2 - 16
7/8n = -14
7n = -14*8
7n = -112
n = -112/7
n = -16
It depends whether it's (3/4)n or 3 / (4n), though.

3/4n + sixteen = 2 - one million/8n subtract sixteen, upload one million/8n to the two factors: 3/4n + one million/8n = -14 problem-unfastened denominators on the left: 6/8n + one million/8n = -14 7/8n = -14 7 = -14(8n) 7 = -112n n = -7/112 n = -one million/sixteen one million/4 - 2/3y = 3/4 - one million/3y upload one million/3y, subtract one million/4 to the two factors: one million/3y - 2/3y = -one million/4 - 3/4 -one million/3y = -one million -one million = -one million(3y) -one million = -3y y = one million/3 - .--

.75N + 16 = 2 - .125N
ADD .125N TO BOTH SIDES
.75N +.125N +16 = 2 -.125N +.125N
.875N + 16 = 2
SUBTRACT 16 FROM BOTH SIDES
.875N +16 - 16 = 2 -16
.875N = -14
DIVIDE .875 ON BOTH SIDES
.875N / .875 = -14 / .875
N = -16
