Question 113157
6x+2y=8
y=-3x
-------
Substitute for "y" in the 1st equation:
6x+2*(-3x)=8
6x-6x=8
0=8
----------
This result means the "x" variable in the two 
equations does not have a single value; the
variables are inconsistent.
So the system is said to be inconsistent.

There is no solution for the system
