1. ## algebra:( i dont understand

hi there! can i please get some assistance on if i'm doing this equation correctly. and if not could i be shown how to do it correctly, it would be a great help!! (the dashed line respresents a fraction)

Question:
2n - 3 = 3
------ ----
2 4

this is how i tried to solve it...

2(2n - 3) = 3
--------- --- x 2
2 4

2n - 3 = 6
---
4

2n - 3 + 3 = 6
--- + 3
4

2n = 6 3
--- + ---
4 1

2n = 6 12
--- + ---
4 4

2n = 18
---
4

2n 18
--- = --- / 2
2 4

n = 18
---
8

= 9
---
4

so i solved for "n" and i got 9/4, is this correct?
thanksss.

2. Hello Frank

I am finding it really difficult to follow the notation you have used for you question.

Now there is a very easy way to check your answer. plug n = 9/4 into the original equation and see if it works.

Now can you please type up the first part of the question using LaTeX

Just click on this $\frac{a}{b} = \frac{c}{d}$ and edit it.
