Question

solve for n.

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

n = 2
n = -2
n = -4
n = 4

Answer 1

Is that 1/(n-4) - 2/n = 3/(4-n) ?

Answer 2

yes sorry

Answer 3

Alrighty that's fine.

Answer 4

First you could take a negative out of n-4 to make it
-(4-n)
Then you could multiply everything by n * (4-n) to get rid of all denominators.

Answer 5

So you would get -n - 2(4-n) = 3n
And that is much easier to solve.

Answer 6

distributing you get -n -8 + 2n = 3n
then we collect n's and constants
2n = -8
n = -4
