Solving Systems of Linear Equation in Three Variable

2x+y-3x=-12
3x-2y-z=3
-x+5y+2z=-3

In the comments going to post image of where I am at. I would like to know if I am going in the right direction with this problem and if not how to correct my errors. Thank you!

Yes you are, now you have to cancel out y from 2 more equations

Yes, and now that you have x and y both as functions of z, you can plug them in any of the 3 equations to get z. After that getting x and y is a piece of cake !
