How many subsets can be formed from the set F?​

32

Step-by-step explanation:

I'm very confirm with my answer mark me as brainliest pl

x= -2

y=0

z= 1

Step-by-step explanation:

{-x+5y-10z=-8

2x-y+10z=6}

{2x-y+10z=6

-7x-3y-10y=4}

{-x+5y-10z=-8

2x-y+10z=6} = x+4y=-2

{2x-y+10z=6

-7x-3y-10y=4} = -5x-4y=10

{x+4y=-2

-5x-4y=-10}. =. y= 0 x= -2

substitute x and y in -x+5y-10z=-8

-(-2)+5(0)-10z=-8

solve for z

z= 1

(x,y,z) = (-2,0,1)

hope this helps
