inconsistent , independent and dependent systems . !


- inconsistent system are typically impoossible to solve , and have statement such as 0=3.

y = x
y = x + 10.





- independent systems two lines might cross at a single point
graph%28+300%2C+200%2C+-20%2C+20%2C+-16%2C+24%2C+x%2B10%2C+2x%29+y = x + 10
y = 2x.

- dependent systems two equations might actually be the same line
y = x + 102y = 2x + 20.
