Solve by substitution or combination/elimination.  What happens?  If you end up with a value for x, hopefully it is either A or B.  If you end up with a (false) statement like 2 = 0, that means there is no solution.  If you end up with a (true) statement like 0=0, then there are infinitely many solutions to this system.
