Question
display the augmented matrix for the
given system. Use elementary operations on equations
to obtain an equivalent system of equations in which x1
appears in the first equation with coefficient one and has
been eliminated from the remaining equations. Simultaneously,
perform the corresponding elementary row
operations on the augmented matrix.
x2 + x3 = 4
x1 − x2 + 2x3 = 1
2x1 + x2 − x3 = 6
