I have a formula that I want to simplify as follows:
(a/x) + (a/y-x)
someone told me that it simplifies to: ax / x(y-x).
If this is right, can someone help me fill in the intermediate steps?
Thanks

If the problem is \(\displaystyle \ \ \dfrac{a}{x} \ + \ \dfrac{a}{y - x}, \ \ \) then you need grouping symbols around the second denominator.
Also, that someone is wrong who told you it simplifies to that expression. And that expression is missing
grouping symbols in its denominator anyway.
"a/x + a/(y - x)" is a correct form.
What is your least common denominator of the two fractions?
The typo is probably in above; should be ay / (x(y-x))
You'll do these exactly the same way you'll solve \(\displaystyle \frac{2}{5} + \frac{3}{7} = ??\)I have a formula that I want to simplify as follows:

Did your math teacher not show how?
