Answer 1

I did !it gave me a weird answer maybe I'm doing it wrong

Answer 2

using 3rd equation try to solve first two

Answer 3

wht u cn do is frm 3rd equation get he value of y in terms of z
place the value of y in terms of z in equation 1 and 2. .
u will get 2 linear equations in z and x. . then solve these :)
