solve the system of linear equations using the Gauss Jordan elimination method
x1 x2+ 4x3 = 15
x1+ x2 = X3 = 4
3X1X2 + X3 = 2

There is probably a typo in the second equation. The first equal sign (between x2 and x3) should be a + or a .
x1+ x2 = X3 = 4
Curiously both corrections using a + or  give integer solutions.
Next, GaussJordan elimination requires the matrix be transformed into a diagonal matrix using elementary row operations. After that, the solution should be evident.
If you are not yet familiar with the method, try reading your textbook, or visit:

If you have questions about the method, give it a try and post up to the point where you have a problem or question.
