1/9+8 3/5 -1/15

what is the answe

Step-by-step explanation:

You must find LCD -  Least Common Denominator

9, 5, 15 - LCD is 45

45 = 9 · 5

45 = 15 ·3

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
