Try substituting (2, 2) into both equations to check if they hold.

It is possible for a system of equations to have no solution.

I am gathering there is no solution because in the second equation it would not be 2 it would be -2...am I right?

Yes.

You can rearrange the equations to get

x + 3y = 8

x + 3y = 4

In that form, there is obviously no solution.
