I need to find out how to solve this integral with the indicated changes/transformations.

int.[0 to 2/3]int[y to 2-2y]

(x+2y)e^(y-x)

dxdy

u=x+2y v=x-y

I know that the xy region is x=y y=0 and y=1- (x/2)

which is a triangle

so I created systems with U and V but can't get a new bounded region...

I just get u=v and two other lines that intersect at the origin.

If anyone can tell me what's up with this it would be helpfull.

Also, does it seem weird that my given v doesn't match the problem exactly?

the u and v were given changes.
