**x =**

3x - y = 2 ...................................... 2

⇒ 9 -y=2

__3__...................................... 13x - y = 2 ...................................... 2

⇒

**y =**

⇒ 6 + z = 4

__7__

2x+z=4 ...................................... 3⇒

**z =**

⇒ w = 21 - 7 =

__-2__

3y-w=7 ...................................... 4

__14__

Hence ,

x = 3

y = 7

z = -2

w = 14

I hope my answer is correct

Thank you Plz mark as the best if you are satisfied!
