The system of linear equations has a unique solution. Find the solution using Gaussian elimination or Gauss-Jordan elimination.
 
2x1 + x2 = 10
2x1 − x2 + x3 = −10
3x1 − 2x2 + 4x3 = −38
(x1x2x3) =

Sorry for late i had just some trouble with my labtop is very low 

2x1 + x2 = 10

2x1 − x2 + x3 = −10

3x1 − 2x2 + 4x3 = −38

after using the method of gauss elimination 

(x1, x2, x3) = (2,6,-8)
