Something like that.

n = -8

Step-by-step explanation:

step 1

8 - 2(3.5n + 2.1) =  3(6.5 - 2.7n) - 24.5

step 2

Let's open the parenthesis first on both sides by multiplying with the outer value/number

8 - 7n - 4.2 = 19.5 - 8.1n - 24.5

step 3

collect like terms

8 - 4.2 - 7n = 19.5 - 24.5 - 8.1n

3.8 - 7n = -8.1n - 5

step 4

collect like terms

-7n + 8.1n = -5 - 3.8

1.1n = -8.8

step 5

1.1n = -8.8

divide both side by 1.1

n = -8.8/1.1

n = -8

the answer is a i belaeve atleast thats what my calculator just gfave me
