Answer:

Explanation:

Solution Steps
Multiply throughout by 10 which is the LCM of the denominators, 5 and 2

Expand the brackets:

The equation becomes:
2n + 5n - 15 = 10n
Add similar terms:
7n - 15 = 10n
Move 15 to the right side:
7n = 10n + 15
Move 10 to the left side
7n - 10n = 15
- 3n = 15
n = -15/3
