Question

Solve the following system of equations using Gauss-Jordan elimination:

 x 1 + x 2 + x 3 + x 4 = 9

2 x 1 + 3 x 2 + 4 x 3 + 7 x 4 = 32

2 x 1 + 2 x 2 + 3 x 3 + 5 x 4 = 24

2 x 1 + 4 x 2 + 7 x 3 + 14 x 4 = 50

In the blanks below, put the value of  x 1  in the first blank, the value of  x 2  in the second blank, the value of  x 3  in the third blank, and the value of  x 4  in the fourth blank.
