Anton, for this kind of problem you have to use parentheses, to avoid double reading!!

So, if second denominator is "x + 2" , then 3/x - 5/(x+2) ....
3            5
——  –  ————  =
x          x + 2

the LCD is  x(x + 2)

3(x + 2)            5x
—————  –  —————  =
x(x + 2)         x(x + 2)

3x + 6 – 5x
—————— =
x2 + 2x

6 – 2x
—————
x2 + 2x

3/x-5/x = -2/x  (Simplify like terms)

-2/x + 2 =?  This is your answer.  You could multiply 2 by x/x and combine the numerators

(-2+2x)/x

It would be a different problem if this were an equation = 0.  But as you have it written, it is an expression.
