Hi
A <i>consistent</i> system has at least one solution.
An <i>inconsistent</i> system has no solutions.
An <i>independent</i> system has exactly one solution.
A <i>dependent</i> system has infinitely many solutions.
x + y = 4
<u>x - y = 6</u>   | Adding 1st and 2nd EQs to eliminate y
 2x = 10
  x = 5  and y = -1    | 5 + y = 4, y = - 1
Independent System (one solution)
CHECKING our answer***
Using x - y = 6
 5 - (-1) = 6
Wish You the Best in your Studies.
