Answer:
or

Explanation:
To solve the expression, we have to simplify it. We are not given x and since this isn't an equation (?=? is an equation), we can only simplify it.
The most we can do is factor out the -3 from the equation. That will make it -3(x-5) in the numerator (since 15 divided by -3 is -5) and -5 still in the denominator. Our new equation is
.
We can take away the negatives by canceling the out and get our answer
. Or if you want to simplify it even more, you can the fraction
out of the equation and get
.
Since we aren't given x, there are infinite solutions for x (all real numbers could be x).
Hope that helped a lot.
