Solving System: 2x+3y-z = 6, 3x-y+z = 1, x+y+z = 1

[dancetolive]

2x+3y-z=6
3x-y+z=1
x+y+z=1

Re: Systems of three linear equations

You might start by adding eqn. 1 to eqn. 2 creating eqn. 4. Then add eqn. 1 to eqn. 3 creating eqn. 5. Now, solve eqns. 4 and 5 simultaneously.

Hello Olive:

Are you trying to solve this system for some course assignment? If so, then what are you currently studying?

PS: Please show whatever work you can if you need more assistance.

Re: Systems of three linear equations

In case you're confused, "adding 2 equations" means this:

3x - y + z = 1
x + y + z = 1
============
4x + 2z = 2
