• after the bank cashed a check maureen wrote for $60, her balance was negative 14 dollars. the equation b + (negative 60) = negative 14 can be used to represent this situation, where b is maureen’s balance, in dollars, before the check was cashed. maureen attempted to solve the equation using the steps below. b + (negative 60) = negative 14. subtract 60 from both sides. b = negative 74. what error, if any, did maureen make? maureen’s work is correct, and her original balance was -$74. maureen should have added 60 to both sides. maureen should have added 14 to both sides. maureen made a computational error when she subtracted 14 minus 60.
