can someone show me how to solve this:
Simplify
3
 + 1
x5

4
1 minus 
x 5
that did n't look right...typo...
here it is its a fraction on top of the other so the top is fine.the bottom should read
one minus (4)/(x5)
Get least common denominator.
For top part, the LCD is x5. So the 1 becomes (x5)/(x5). Thus the top becomes (3 + x  5)/(x  5). This simplifies to (x2)/(x5).
Now do the bottom. The LCD is x5. So the 1 becomes (x5)/(x5). So, the whole bottom part becomes (x54)/(x5).
This simplifies to (x9)/(x5).
Now you have complex fraction, where the top is: (x2)/(x5); and the bottom is (x9)/(x5). The (x5)'s cancel, so you're left with:
(x2)/(x9).
