Question:
+%28+5x%2F%28x-7%29+%29-+%2835+%2F%28x-7%29%29
Answer:

+%28+5x%2F%28x-7%29+%29+-+%2835+%2F%28x-7%29%29 = +%28+5x%2F%28x-7%29+%29+-+%2835+%2F%28x-7%29%29


Here the denominators are same...so you can directly subtract the numerators...

==> +%285x+-+35+%29%2F+%28x+-+7+%29


Take our common term of the numnerator....


==> +5+%28x+-+7+%29%2F+%28x+-+7+%29


Now you have (x-7) is common in both the numeraor and the denominator..

So it will get cancelled....

==> answer is 5



That is +%28+5x%2F%28x-7%29+%29-+%2835+%2F%28x-7%29%29 = 5



Hope you found the explanation useful....
