Question

9n - 6 = 5n + 18
Solve

Answer 1

9n - 6 = 5n + 18
- 5n on both sides
4n - 6 = 18
Subtract 6 on both sides
4n = 12
Divide both sides by 4
n = 3

Answer 2

n = 6

Explanation:

9n - 6 = 5n + 18

Subtract 5n from each side

9n-5n - 6 = 5n-5n + 18

4n -6 = 18

Add 6 to each side

4n -6+6 = 18+6

4n = 24

Divide each side by 4

4n/4 = 24/4

n = 6
