How do you solve #3y-z=-1#, #x+5y-z=-4#, # -3x+6y+2z=11# using matrices?
Use Cramer's Rule (with Determinants) to get
Using the coefficient of
Cramer's Rule tells us that:
An interesting point to observe, because of the way computers perform (what is called "floating point") arithmetic the value of
which, in turn, cause
You must be prepared to apply reasonable interpretations when working with computer generated outputs.
