Answer 2

Answer:

x+y=8—(1)

x+z=13—(2)

z-w=6—(3)

w+y=8—(4)

Subtracting eqn 1 from eqn 2 we get,

x+z-x-y=13–8

z-y=5—(5)

Adding eqn 3 and eqn 4 we get,

z-w+w+y=6+8

z+y=14—(6)

Adding eqn 5 and eqn 6 we get,

z-y+z+y=5+14

2z=19

z=9.5

Putting this in eqn 6 we get

9.5+y=14

y=4.5

Putting this in eqn 1 we get,

x+4.5=8

x=3.5

Putting y in eqn 4 we get,

w+4.5=8

w=3.5

This is the solution.
