Solve the system analytically (systems in 3)?
x-y=8
x-z=8
y+z=8
I know the answer is (12,4,4) but I don't know how to solve it. I know I have to solve 2 of the equations for one variable and then plug in but I'm not sure how. I'm used to x+y+z=# type style equations.

x - y = 8
x - z = 8
y + z = 8
x = y + 8
x = z + 8
z = x - 8
z = -y + 8
2x = y + z + 16 = 8 + 16
x = 12
Solution:
x = 12, y = 4, z = 4
