3x/(3x + y) is already in its simplified form, there's nothing more you can really do. You can't cancel anything out and nothing factors. You could algebraically manipulate it to write it other ways, but as far as I can tell there's nothing more you can do to simplify it.
NOTE ABOUT SOME OF THE OTHER ANSWERS: You CAN'T cancel out the 3x in the numerator and the 3x in the denominator. 3x/(3x + y) is NOT equal to x/y. Think about it this way...6/(6+4) simplifies to 6/10 = 3/5. But 6/(6+4) is NOT equal to 1/4 (if you attempted to cancel out the 6's). 3/5 isn't equal to 1/4. So 3x/(3x+y) is not equal to x/y. If it were 3x/(3x + 3y) THEN you could cancel the 3's and be left with x /(x + y).

This expression is already in its most simplified form. Nothing to do here.
The question is 3x divided by (3x+y).
Now IF the problem were 3x / (3x+3y), you could factor out the threes in the denominator like this:
3x / 3(x+y) and cancel the threes, so that the answer would be x/(x+y).

I may or may not be wrong, but divide the bottom 3x into the top 3x, to make 1 over y, y being positive of course.
3x over 3x is equal to 1 over 1. 3x over 3x + y is like 1 over 1 + y, if that makes any sense... the 3x cancels eachother out.
Now, of course, I learnt this from an idiotic teacher who also said something about 1/7 is equal to 7/1. *rolls eyes* So, again, I may or may not be right.

3x/(3x+y) is already simplified simply because 3x and 3x+y do not share a common factor. you can only simplify a fraction if and only if the numerator and the denominator share a common factor.

3x over 3x+y is the same as saying:
3x devided 3x
plus
3x devided by y
in other words:
1
plus
3x over y
Answer: 1 + 3x / y
(slash is used to seperate top and bottom number of a fraction)
nothing is cancelled out

the least complicated technique to confirm complicated fractions is to invert the backside fraction and multiply by utilising the perfect fraction: [(x+4)/y] / [7/3x] [(x+4)/y] * [3x/7] (3x)(x+4)/7y (3x²+12x)/7y

you cancel out 3x, so ur left with the y. simplified!

3x/(3x+y) = 1- y/ (3x+y) but it is not so simplified
