The key here is to remember how to get rid of the parentheses. The 'minus sign' ( - ) before the parentheses says that in order to get rid of them, you have to change the sign of each term inside. -3a - (5 - 6a) is the same as -3a -5 + 6a Add up the (-3a) and the (+6a) and you have +3a . So the whole thing becomes 3a - 5 .
