Question

(5/5x-1)-(1/1-5x)

Answer 1

\[\frac{5}{5x - 1} - \frac{1}{1 - 5x}\]

Do you know what to do first?

Answer 2

not sure...been out of school way too long. im just trying to help a friend with her homework

Answer 3

When subtracting fractions, the denominators must be the same before subtracting.

Answer 4

Can you think of a way to make both denominators the same?

Answer 5

What if we re-wrote it this way:

\[\frac{5}{5x - 1} - \frac{1}{-5x + 1}\]

Do you see anything we can do from there?

Answer 6

they cancel each other out so its just 5-1 right?

Answer 7

Actually, the next step is to do this:
Factor out a negative:

\[\frac{5}{5x - 1} - \frac{1}{-(5x - 1)}\]

Then this:

\[\frac{5}{5x - 1} - \left(-\frac{1}{(5x - 1)}\right)\]

To get this

\[\frac{5}{5x - 1} + \frac{1}{5x - 1}\]

Now the denominators are the same and you can add.

So solving this is a matter of how well you are able to play with negatives.

Answer 8

is the final answer 6/10x-2

Answer 9

Remember, when adding fractions you only add the numerators. The denominator remains the same.

Answer 10

6/5x-1

Answer 11

6/(5x - 1)

Answer 12

That's how you write it horizontally. Vertically you write it like this:

\[\frac{6}{5x - 1}\]
