1.) Solve the following system by substitution or elimination method.

2x - 4y + z = -7
-2x + 2y - 3z = 4
x + 2y - z = -3


2.) Solve the system by matrix method.

3x + y + 2z = 7
2x + y + z = 6
x - y - z = -3
3.) Solve the system by matrix method.

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

I suck at math.

You have a fucking incredible magical organ in your head. The shit is allows you to comprehend and do is fucking stunning.

These stupid little questions are nothing compared to what you can potentially understand. If you stop trying at this level of *difficulty* you're wasting a huge chunk of yourself.

If the above doesn't help, consider watching the other videos in the "Systems of equations and inequalities" section. These videos are very well regarded.

Confirmed for physicist or how I like to call it: pseudo-scientist.
Everyone knows the only hard science is mathematics and most physicsfags fail their math courses.

One of the purposes of schools is to filter out the retards who are destined to go into lower jobs instead of studying. You better learn to deal with it.
