To simplify this expression, first find a common denominator for the fractions:

(х-5х/х+2) + (х-3/х+2)

Combine like terms in the numerator of the first fraction:

(-4х/х+2) + (х-3/х+2)

Now, combine the fractions:

(-4х + х - 3)/(х + 2)

Combine like terms in the numerator:

(-3х - 3)/(х + 2)

So, the simplified expression is (-3х - 3)/(х + 2)
