Solve the system:
3x-2y+2z=5
6x+3y+2z=-1
9x-y-4z=5
There are about 7 or 8 different methods to
solve systems of equations and students study them all
at different times in algebra. I'll give you just the
answer because if I picked one of them to show you, it
would likely be one of the methods you are not studying,
so please post again, and let us know which one of the
many ways to solve these you are studying now.
