Question

Expand the expression and combine like terms:
1/7 - 3 (3/7n - 2/7)

Answer 1

- 9/7n+1

Explanation:

1/7 - 9/7n + 6/7 =

= 1/7 + 6/7 = 7/7 = 1

-9/7n+1

Answer 2

`(1)/(7) - 3( (3)/(7) n - (2)/(7)) \\ \\ (1)/(7) - 3( (3n)/(7) - (2)/(7) ) \\ \\ (1)/(7) - 3 * (3n - 2)/(7) \\ \\ (1)/(7) - (3(3n - 2))/(7) \\ \\ (1-3(3n - 2))/(7) \\ \\ (1-9n+6)/(7) \\ \\ (-9n + 7)/(7) \\ \\ 1 - (9n)/(7) \\ \\`

The final result is: 1 - 9n/7.
