Hi, I'm working on a u substitution problem so that.

u = 3-x

so that

du = (-1) dx ,

or

(-1) du = dx .

With these equations you just switch content from one side to the other with no problems?

Thanks,

Tim

The manipulations you've done there are all fine. You just need to obey the rules of algebra. Algebra doesn't go away when you start studying calculus - indeed, calculus packs down your algebra!

Yop, I see it now.
