Question

Can someone help me with this system of linear equation, it's somewhat stated confusingly. I'll also upload a photo.

Answer 1

I want to know if I do the whole process of eliminating x from the 2nd eq., then the 3rd eq? Or do I just eliminate x from the 3rd eq. by doing whatever(+or-) the 3rd eq. from the 2nd eq.?

Answer 2

it is very easy

Answer 3

you have:
2x-y+3z=2
x+2y-z=4
-4x+5y+z=10

Answer 4

first of all multiple 2 in equation One and then plus it by equation third
you can see that x value eliminate.
and so on.
ok?
