Given the system of equations, solve for x,y,z.
2x + y + z = 6
x + 2y + z = 12
x + y + 2z = 24

Subract the first two equations from one another
solve for x in the equation
go back and substitute for x and reapeat the process until you have completely solve the system.
Does that help?
ok...I plugged in x to find that y = -12 + z.
Is this correct?
Then, would z = y + 12? How will I find the numerical values of x,y, and z?
Make your life easier and simplify where you can.
Now just keep substituting.
