## GJE uses one or more elementary row operations to reduce matrix

*A*to the identity matrix.## The RHS of the generalized equation becomes the solution set and

*Y*becomes*A*-1.## Disadvantages:

- Requires all
**b***i*'s to be stored and manipulated at same time memory hog. - Don't always need
*A*-1.

- Requires all
## Other methods more efficient, but good backup.
