Answer:
3.5+4.5=8
3.5+9.5=13
9.5-3.5=6
Step-by-step explanation:
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
