At the end of the current year a company has total assets of $14,700 and total liabilities of $8,680.

If during next year total assets increased by $4,300 and equity decreased by $3,500, what would be total liabilities at the end of next year?

I'm just not sure how to go about solving this problem.

assets - liabilities = equity just plug the figures into the equation i.e. (14700+4300) - ((14700-8680)-3500) =??
