simplify if possible : 1-v/v-9-5v-7/9-v
:
I assume the problem is:
%28%281-v%29%29%2F%28%28v-9%29%29-%28%285v-7%29%29%2F%28%289-v%29%29
We can make the denominators the same by factoring out -1
%28%281-v%29%29%2F%28%28v-9%29%29-%28%285v-7%29%29%2F%28-1%28v-9%29%29
the minus 1 changes the sign to
%28%281-v%29%29%2F%28%28v-9%29%29+%28%285v-7%29%29%2F%28%28v-9%29%29
Now we can put it over a single denominator, since they are the same.
Then remove the brackets and combine like terms
%28%281-v%29%2B%285v-7%29%29%2F%28%28v-9%29%29 = %28%284v-6%29%29%2F%28%28v-9%29%29
