Question 39759: Gauss Jordan...Please Help
A system of three linear equations in the variables x,y and z is represented by an augemented matrix. The first two rows of this augmented matrix are shown. Using the Gauss Jordan method to solve the system, the next step is to make the entry in row 2, column 1 equal to zero by multipling row 1 by a constant and adding that result to row two. Now I am stuck I keep not getting the right answer to complete row two of the new augmented matrix...

Yes, what you do is multiply the top row by -4 and add it to the second row, but leaving the first row alone...you get
1 3 4 2
0 -7 -9 1
