Write two expressions (with at least two terms each) that when added together have a sum of -4n + 6.

The terms involving n and the constant terms will be summed on their own, so we can simply think of two terms that sum to -4n, and two numbers that sum to 6.

For example, we can choose 3n and -7n for the literal part, and 2 and 4 for the constant part:

Try to choose another two terms that sum to -4n, and two other numbers that sum to 6, to build the second expression.
