Find/solve following system of linear equations,(adsbygoogle = window.adsbygoogle || []).push({});

3y_1 + 2y_2 +y_4 = 6

5y_1 - 2y_2 +2y_4 = 5

-2y_1 + y_2 - y_4 = -2

WORK DONE :

I am told that the answers are y_1 = 1 and y_2= 1 and y_4 = 1.

But i dont understand how to obtain these values....

I know how to solve 2 linear systerm of equations...but how do i solve

3 linear system of equations like the one above?
