its (x-5)/(5-x)

(x-5)/(5-x) = -1*(5 - x)/(5 - x) = -1*1 = -1

Well, the numerator "x-5" can also be written as "-1(-x+5)" or "-1(5-x)." You get this by doing the reverse of the distributive property.
Now the problem is -1(5-x/5-x).
5-x/5-x = 1.
-1(1) = -1
Therefore, the simplified version of the problem would be "-1."

Amazing! Even if you meant (x - 5)/(5 - x), but forgot the parentheses, you get the same result.
x - 5/5 - x = x -1 -x = -1
If you meant to write the expression this way, it is much cooler, because you do not have to make sure the denominator is non-zero.

x-5=-(5-x), so (x-5)/(5-x) = -(5-x)/(5-x) = -1, assuming xâ 5.
