Solve (3 3/8) to the power of -1

[Nicholasw]

How would I solve these equation:

(3 3/8) to the power of -1

3X / X-1 + 4 = X / X+1

5 / X+2 + X(X+3) / X (Square) - 4

I been really stuck on these.

Thanks

What have you tried to do? I notice that you haven't even told us what you are supposed to do! You say "How do I solve these equation?" but only one of them is an equation! I can make a few guesses.

Can you write 3\frac{3}{8} as a single, improper, fraction? Do you know what a -1 power does to a fraction? (\frac{a}{b})^{-1}= ?

Do you mean 3X/(X-1)+ 4= X/(X-1)? What happens when you multiply a fraction by its denominator?

5 /(X+2) + X(X+3) / X² - 4 or 5/(X+2)+ X(X+3)/(X²-4)?
What were you told to do with this?
