Final answer:
To simplify the sum (8x+5)/(x-4)+(7x+2)/(x-4), combine the numerators over the common denominator.
Step-by-step explanation:
To simplify the sum (8x+5)/(x-4)+(7x+2)/(x-4), we can combine the numerators over the common denominator.
The numerator of the first fraction (8x+5) can be added to the numerator of the second fraction (7x+2) since they have the same denominator (x-4).
The simplified sum is (15x+7)/(x-4).
