-x over 3 can not be simplified.

3 x 3 x 3 x 3 x 3 x 3 x 3 That's much simpler than 37 .
The volume would be (x-3)*(x-3)*(x-3), i.e. (x-3)^3. This can be multiplied out and simplified.

-x over 3 can not be simplified.
2 x 2 x 3 x 3

It is: x-1+4+7x-3 = 8x simplified
3 x 3 x 3 x 3 x 3 x 3 x 3 That's much simpler than 37 .
x^2-x-6
2x+x-3 can be simplified to 3x-3
y = 1/2 x - 3/2
The volume would be (x-3)*(x-3)*(x-3), i.e. (x-3)^3. This can be multiplied out and simplified.
Any fraction of the form x/(3*x) where x is not a composite number.

Sqrt(x-3) or even sqrt(x)-3 cannot be simplified. And without the value of x, they cannnot be evaluated.
