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
