Convert the system

to an augmented matrix. Then reduce the system to echelon form and determine if the system is consistent. If the system in consistent, then find all solutions.

Augmented matrix:

Echelon form:

Is the system consistent?

Solution:

**Help:** To enter a matrix use ** [[ ],[ ]] **. For example, to enter the

you would type [[1,2,3],[6,5,4]], so each inside set of [ ] represents a row. If there is no free variable in the solution, then type
