What Exercise Machine is good for someone who needs Cardio AND Weight Lifting?

As the other answer stated, it would take more than one machine but if you have a gym nearby you may have access to all of the machines they have there. You might look to see if there is a cross-fit facility near you since I think those exercises may work for both and certainly for weight lifting. Google Christmas Abbott and see what that has done for her!! You could take up jogging for the cardio perhaps and as far as weight lifting you can do things like push ups or lift things around the house for a number of repetitions to build up muscle, for example a gallon jug filled with sand or water a number of times. Here is a link regarding crossfit which gives you some info on that and if you look around elsewhere on the livestrong site you can get some other good information regarding exercises.

No, you are actually going to have to use more than one machine.
