Barbara Holden · Answer 1

First you combine like terms. Adding 5n and 4n together to get 9n+3=30. Then you subtract 3 from 30 and end up with 9n=27.

Then you divide 27 by 9 and end up with n=3.

So the answer is 3.

N=3

5n+3+4n=30 (add 5n and 4n)

9n+3=30 (Subtract 3 from both sides)

9n=27 (divide both sides by 9)

n=3
