2.) If x > 2, then x^2– x – 6 over x^2 - 4=

3.) 4 – (-6) over -5 =

4.) If 2x – 3(x + 4) = - 5, then x =

5.) – 3(5 – 6) – 4(2 – 3) =

I know, it's elementary algebra and it's bad I can't even solve 'em, I just don't remember how too!
It's not for homework, it's for a placement test. So any help will do. Thank you!
