Question

3/4-1/2n=5/8

Answer 1

(3/4)-1 / 2n = 5/8

-1/4/2n =5/8

-2/8/2n=5/8

-2/8 = 10/8 n

(-2/8)/(10/8) = n

-16/ 80 =n

-1/5=n

Answer 2

is it 3/4 - (1/2)n = 5/8
or 3/4 - 1/(2n) = 5/8 ??

Answer 3

If it is the first way, then it is this...
3/4 - (1/2)n = 5/8 -- multiply the equation by 8
6 - 4n = 5 -- subtract 6 from both sides
-4n = -1
n = 1/4

check...
3/4 - 1/2(1/4) = 5/8
3/4 - 1/8 = 5/8
6/8 - 1/8 = 5/8
5/8 = 5/8 (correct)

Answer 4

your right, my bad

Answer 5

easy mistake to make...don't worry about it.

Answer 6

N= 1/4
