now THIS seems impossible.

A number subtracted by 13 gives the quotient of 30 and -3. What is the number?

Anyone have a clue? I don't mean to post so many questions.. I just need help, that's all.

This works similarly to the other "numbers" word problem you posted. Follow the same procedure as displayed in the full solution you were provided. Pick a variable and... then what?

Please reply showing how far you have gotten. Thank you.
