find all nonnegative integer solutions of the system
if t=0, we have
so, 0<x<8, y<8-x, z<8
List them all.
If t=1, change the 8's to 7's in the first 3 conditions.
And so on, up to t=7:
(x,y,z,t) = (0,0,0,7)
Don't see the point of the exercise, but there it is.
sory a mistake, the corect one problem is find all nonnegative integer solutions of the system
