## Homework Statement

ive been given this system of equations and told to solve it:

x+2y+2z=-3

2x+y+z=0

x-y-iz=i

## Homework Equations

all elementary row operations

## The Attempt at a Solution

1 2 2|-3

2 1 1| 0 row2-row1 then row2 x -1/3

1-1-i| i

1 2 2|-3

0 1 1|-2 row3-row1 then row3+3 x row2

1-1-i|i

1 2 2|-3

0 1 1|-2

0 0 5-i|-3+i

at this point im stuck, i know i have to get it in reduced row echelon form, but that 5-i has got me scratching my head, and somehow i know i have to get it to be 1 in order to reduce the other rows.
