Question 56483: I'm just trying to find out how to solve this problem which is a rational expression:
5/(2x-4) - 3/(2-x)
Answer by funmath(2933) (Show Source): You can put this solution on YOUR website!
In order to add or subtract fractions you must have a common denominator. First factor where you can:
The second fraction has a denominator with a factor of -1, mutliply the numerator and denominator by -1.

The LCD is 2(x-2), whatever you do to the denominators to get that you also have to do to the numerators.

Now you can combine the numerators.

Happy Calculating!!!
