SOLUTION: Solve the equations by substitution. If the equations are inconsistent and the solution is an empty set, write "no solution".
x - y = 6
x = y + 2

Substitute for "x" and solve for "y":
(y+2) - y = 6
2 = 6

That happend because we assumed there was an (x,y) pair
that saisfied both equations.
There is no such point.

The equations are inconsistent.
