<PRE><B>Question 164243</B>
A system is consistent if there is at least one solution. 
for example x+y=1 and 3x+y-2

 A system is inconsistent if it has no solutions 
(When the equations are inconsistent, it is possible to derive a contradiction from the equations, such as a proof that 0 = 1.)
for example  3x+7y=3 and 3x+7y=10


A system of equations are dependent if both the equations represent the same equation
for example 2x+3y=2 and 4x+6y=4
