Answer 2

Answer:

x = 15/11 or x = 13/5

Step-by-step explanation:

I'm going to assume that the expression is equal to 0:

(11x - 15)(5x - 13) = 0

By the zero identity, if either 11x - 15 or 5x - 13 is equal to 0, that will make the equation true. So, let's set each one equal to 0:

11x - 15 = 0  ⇒  11x = 15  ⇒  x = 15/11

AND

5x - 13 = 0  ⇒  5x = 13  ⇒  x = 13/5

Thus, x = 15/11 or x = 13/5.

Hope this helps!
