Answer:
n = 2.5
Step-by-step explanation:
6 + 6n = 21
Subtract 6 from each side
6-6 + 6n = 21-6
6n = 15
Divide each side by 6
6n/6 = 15/6
n = 2.5
6 + 6n = 21
subtract 6 from both sides which will leave you wit 6n = 21 - 6 because 6-6 cancels out.
then subtract 21 from 6 which will leave you with 6 = 15. then divide 6 from both sides which will leave you wit n= 2.5
n = 2.5
subtract 6 from both sides which will leave you wit 6n = 21 - 6 because 6-6 cancels out.
then subtract 21 from 6 which will leave you with 6 = 15. then divide 6 from both sides which will leave you wit n= 2.5
n = 2.5
