Answer:
x=1
y=2
z=-1
Step-by-step explanation:
Add the first two equations: (this will be equation 4)
Multiply the first equation by 2:
Take the third equation and subtract the above equation.
Multiply that by 3:
Subtract equation 4:
For y+3z=-1, plug in values:
Plug in y and z values in first equation:
