Answer:
Expanding form
\(\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}\)
\(1-\frac{9}{7}n\)
Step-by-step explanation:
We are given that \(\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})\)
We have to expand the terms and combine like terms
\(\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}\)
Expanding form
\(\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}\)
In the given expression like terms are \(\frac{1}{7}\)and \(\frac{6}{7}\)
\(\frac{1}{7}+\frac{6}{7}-\frac{9}{7}n\)
\(\frac{1+6}{7}-\frac{9}{7}n\)
\(\frac{7}{7}-\frac{9}{7}n\)
\(1-\frac{9}{7}n\)
