Homework Statement
Calculate the volume of the body that is bounded by the planes:
x+y-z = 0
y-z = 0
y+z = 0
x+y+z = 2
Homework Equations
The Attempt at a Solution
I made a variable substitution
u = y+z
v = y-z
w = x
which gave me the new boundaries
u+w = 2
v+w = 0
v = 0
u = 0
Problem is, I must have slept late the day they taught this is class. What do I do to determine which way these inequalities go?!?
