Question

help ):


Solve the following system of equations.

2x + 3y – z = 1
3x + y + 2z = 12
x + 2y – 3z = –5

Answer 1

i have it plugged in my calculator in the matrix thing but i don't know how to get the answers from there

Answer 2

Actually I have an even simpler suggestion if I may, solve for x on the 3rd equation then plug into the first two, simplify, then literally line up the first two equations and add them

Answer 3

Do you follow that? ;D

Answer 4

You can get everything in terms of z & y easily enough
