y=6+4
Consider the first equation. Add 4 to both sides.
y=10
Add 6 and 4 to get 10.
-z=9-8
Consider the second equation. Subtract 8 from both sides.
-z=1
Subtract 8 from 9 to get 1.
z=-1
Divide both sides by -1.
-x=12-10
Consider the third equation. Subtract 10 from both sides.
-x=2
Subtract 10 from 12 to get 2.
x=-2
Divide both sides by -1.
y=10 z=-1 x=-2
The system is now solved.
