Can you use the subjunctive backwards?
I'd always known how to use the subjunctive, but a question had came upon me today when I was using the phrase, "Tengas que comerla, antes de que tú madre viene," and when I'd said it, I was questioning myself because I'd sounded wrong and backwards, but my question is to you is, can you used the subjunctive backwards.
Example: Tengas que limpiar el baño. or Tengas que limpies el baño.

Not in the cases that you mention because you're using the subjunctive mood with the wrong verb. If you mean "Can I use subjunctive at the end of a sentence?" then, yes, you can.
Tengas que comerla, antes de que tú madre viene," = incorrect
Tienes que comer antes de que tú madre venga" = correct
In this example below no subjunctive is required....
Tengas que limpiar el baño. or Tengas que limpies el baño. = incorrect
Tienes que limpiar el baño. = correct
Here it's required...
Es importante que limpies el baño = correct
Gracias para me ayudabas.
