Thank you for the opportunity to help you with your question!
To rewrite this all you have to do is multiply -2 and c which is -2c and then multiply -2 and -y which is 2y (two negatives make a positive). Put the two together and you have -2c + 2y. That is your answer.
Please let me know if you need any clarification. I'm always happy to answer your questions.
