augmented matrix row reductions

Posted by jemma franklin on September 22, 2002 at 15:25:42:

Hi guys. Ive been able to answer these type with less variables but these have me stumped. They are supposed to be answered using augmented matrix in row reduced echelon form. Any help would be great!!..

x + 2x + 3x + 5x - 3x = 34
5x + x + 5x + 7x + x = 21
7x - 3x + x - 2x + 2x = 33
x + 5x - 2x - 14x - 4x = 11

and

x + 2x + 3x + 5x - 3x = 34
5x + x + 5x + 7x + x = 21
7x - 3x + x - 2x + 2x = 33
x - 6x - 7x - 14x + 4x = -20
