Final answer:
To perform the expression, combine the two fractions with a common denominator and simplify the numerator. The simplified expression is (5u - 14)/(v+5).
Step-by-step explanation:
To perform the given expression, we need to combine the two fractions with a common denominator. In this case, the common denominator is (v+5). So, the expression becomes:
(8u-9)/(v+5) + (-3u-5)/(v+5)
Next, we can combine the numerators of the fractions:
(8u-9+(-3u-5))/(v+5)
Simplifying the numerator gives us:
(8u - 9 - 3u - 5)/(v+5)
Combining like terms:
(5u - 14)/(v+5)
Therefore, the simplified expression is (5u - 14)/(v+5).
