I don't know what course or level you are in, but when I studied Linear Algebra, the author was quite clear that the quickest, most efficient method is Gaussian Elimination.

i just need the solution

anonymous · Answer

We tutors can't just give out answers.  We have to abide by the requirements of the site which direct us to showing the students how to get the solutions themselves.  To that end, I can direct you to eliminate "x" from equation #2 and #3.  As a start.

You eliminate "x" from the second equation by adding the negative of the first equation to the second equation.  "x" will drop out.  You add double of the negative of the first equation to the 3rd, and again, "x" will drop out.
