Answer 1

Answer:

  1 -9/7n

Step-by-step explanation:

  $\dfrac{1}{7}-3\left(\dfrac{3}{7}n-\dfrac{2}{7}\right)=\dfrac{1}{7}-\dfrac{3\cdot3}{7}n+\dfrac{3\cdot2}{7}=\dfrac{1}{7}+\dfrac{6}{7}-\dfrac{9}{7}n\\\\=\dfrac{1+6}{7}-\dfrac{9}{7}n=\boxed{1-\dfrac{9}{7}n}$

Answer 2

Answer:

1 - (9n/7)

Step-by-step explanation:

1/7 - 3(3/7n - 2/7)

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

1 - 9n + 6/7

1 - 9n + 6/7

7 - 9n/7

7/7 - 9n/7

1 - 9n/7
