If you mean: 6y-4y then it simplifies to 2y.
Think of it as 6 yams - 4 yams. The answer will be in yams ... 2 yams.
6y - 4y = 2y
No, probably not.
6xy^2z^2 over 6xy^4z^4 or 1 over y^2z^2

The answer is 20.you get this answer by reading the instructions.
2/y
No, probably not.
6xy^2z^2 over 6xy^4z^4 or 1 over y^2z^2
-5+y
Y plus Y = 2Y simplified
6y
3y
y2-x2 = (y+x)(y-x)
If Y = y, then it is 9y4 or 9Y4. If Y is not the same as y, then you can't simplify it any.
