How do you Simplify the expression n plus 2n plus 2?
Combine like terms to give 3n + 2
What is the simplified form of -6n plus 2 plus 3n-3?
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)
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
How do you solve n - 16 equals 2n plus 12 plus 3n?
This can be solved by grouping all terms with "n" in them on one side of the equation, and all other terms on the opposite side, then adding together like terms, and dividing both sides by the remaining coefficient of "n": n - 16 = 2n + 12 + 3n ∴ n - 2n - 3n = 12 + 16 ∴ -4n = 28 ∴ n = -7
