Question 372243: I am confused about this problem I have.This is the equations: x-y+2z=5
3x+2y=4
-2x+2y-4z=-10
Can this be solved even though the second equations doesn't have a "z" value?

Yes. It simply means the coefficient of z in the 2nd equation is 0, so that essentially the equation is 3x + 2y + 0z = 4.
