Question

Can you show me how to do this, it makes no sense.(2c/c-4)-2=(4/c+5)

Answer 1

The answer is -14, but how do you solve that?

Answer 2

\[\frac{2c}{c - 4} - 2 = \frac{4}{c + 5}\] Right?

Answer 3

Yes

Answer 4

Okay

\[\frac{2c}{c - 4} - \frac{4}{c + 5} = 2\]

Do you know how I got that?

Answer 5

Yes you added 2 to both sides

Answer 6

Then I subtracted \(\dfrac{4}{c + 5}\) from both sides.

Answer 7

Then you subtracted 4/c+5

Answer 8

Yes

Answer 9

So now, I have to subtract the fractions, except they don't have the same denominator.

Answer 10

Correct

Answer 11

Just a quick question...

How would you subtract
