Use elimination to solve each system of equations.
x+y2z=10
8x9yz=5
3x+4y+2z=10
I need to figure out what x,y, and z each equal. I must use the elimination method.

Marth,
The goal here is to 1st form 2 equations containing 2 variables, then use those to eliminate another variable.
The first 2 equations can be formed from any 2 of the given equations.
