Add the linear expressions 7(n-2)+5(n+4)+3(n(1)

Answer 1

To add the linear expressions, we need to simplify the terms and then combine like terms.

Starting with 7(n-2):

7(n-2) = 7n - 14

Next, we simplify 5(n+4):

5(n+4) = 5n + 20

Finally, we simplify 3(n(1)):

3(n(1)) = 3n

Now, let's combine the like terms:

(7n - 14) + (5n + 20) + 3n

Combining the n terms:

7n + 5n + 3n = 15n

Combining the constant terms:

-14 + 20 = 6

Therefore, the sum of the linear expressions is:
15n + 6
