9/x-1+5/x+4

1 answer

To add these two fractions, we first need to find a common denominator. In this case, the common denominator is x(x+4).

So, we rewrite the fractions with the common denominator:

(9(x+4))/(x(x+4)) + (5x)/(x(x+4))

Now, we can add the numerators:

9(x+4) + 5x = 9x + 36 + 5x = 14x + 36

Therefore, the sum of the two fractions is:

(14x + 36)/(x(x+4))
