Answer 2

It appears that you want to simplify the expression:

N - 3n + (-1.5) + 1.8 + (-1.7) + 5.9

To do this, you can first combine like terms:

N - 3n - 1.5 + 1.8 - 1.7 + 5.9

Now, let's add or subtract the numbers:

N - 3n - 1.5 + 1.8 - 1.7 + 5.9 = (N - 3n) - 1.5 + 1.8 - 1.7 + 5.9

Now, combine the constants:

(N - 3n) + (-1.5 + 1.8 - 1.7 + 5.9)

Now, calculate the constant part:

-1.5 + 1.8 - 1.7 + 5.9 = 4.5

So, the simplified expression is:

(N - 3n) + 4.5
