Answer 2

To simplify the expression -7m - 15n + 3m + 18n, we can combine like terms.

The terms with "m" are -7m and 3m. When we combine them, we get -7m + 3m = -4m.

Similarly, the terms with "n" are -15n and 18n. When we combine them, we get -15n + 18n = 3n.

Putting it all together, the simplified expression is:

-7m - 15n + 3m + 18n = -4m + 3n
