Step-by-step explanation:

2x-y+z =-2

x+3y -z =10

x+2z =-8

Multiply the first equation  by 3 so we can eliminate y

3*(2x-y+z) =-2*3

6x -3y +3z = -6

Add this to the second equation

6x -3y +3z = -6

x+    3y -z    =10

7x   +2z      =4

Multiply this equation by -1

-7x-2z = -4

Add the third equation

-7x-2z = -4

x+  2z =-8

-6x    = -12

Divide by -6

-6x/-6  = -12/-6

x = 2

Now we will find z

x+2z = -8

2+2z = -8

Subtract 2 from each side

2-2+2z= -8-2

2z=-10

Divide by 2

2z/2 = -10/2

z= -5

Now we need to find y

2x-y+z =-2

2(2) -y+-5=-2

4 -y-5 = -2

Combine like terms

-1 -y = -2

Add 1 to each side

-1+1 -y =-2+1

-y = -1

Multiply by -1

y = 1

x=2 y=1 z=-5
