Answer

$\frac{3}{2}n$

Work Step by Step

We first apply the distributive property. Then, we simplify the resultant expression: $2n-\frac{6}{7}n+\frac{5}{14}n$ =$n(2-\frac{6}{7}+\frac{5}{14})$ =$n(\frac{2(14)-6(2)+5(1)}{14})$ =$n(\frac{28-12+5}{14})$ =$n(\frac{16+5}{14})$ =$n(\frac{21}{14})$ =$\frac{3}{2}n$
