Answer 5

What have you tried to do?

Answer 6

I already figured it out and the answer is (-1,0,-4) the problem is that I did not write in an orderly fashion.... I don't know how to organize these systems to make it neat on paper.

Answer 7

You can solve it using \(\Huge\color{blue}{ \sf matrix }\), that's what I would do and suggest to anyone.

glad you figured it out though :)

Answer 8

Well I was trying to figure out how to solve it using the triangular-system method used in my book, but I don't understand how to use it.

Answer 9

don't understand the method^^

Answer 10

it's just like matrix, but they write it in a different format. It seems confusing, but only seems...
