Simplify -6n+2+3n-3 So first let's combine the n terms. -6n and 3n is -3n since -6 and 3 is -3. Or, think of being in debt 6 dollars as -6n and someone gives you 3 dollars just because they are nice like those people who answer WikiAnswers.com. Now you are only in debt 3 dollars which we denote as -3 and n could be dollars or cents. Bottom line, when you combine the n's it is -3n. Next combine the numbers or constant terms, 2-3 is the same as 2+ (-3) which is -1. So the answer is -3n-1 which can also be written as -(3n+1)

It is: 4n-13
12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
To simplify the expression (10n - 4n), you combine the like terms. Subtract (4n) from (10n) to get (6n). Therefore, the simplified expression is (6n).
