Answer:
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
