$1\frac{2}{7}$

#### Work Step by Step

The phrase "Subtract (3z-$\frac{3}{7}$) from (3z+$\frac{6}{7}$)" can be translated into the expression: (3z+$\frac{6}{7}$)-(3z-$\frac{3}{7}$) Simplify: (3z+$\frac{6}{7}$)-(3z-$\frac{3}{7}$) =3z+$\frac{6}{7}$-3z+$\frac{3}{7}$ =3z-3z+$\frac{6}{7}$+$\frac{3}{7}$ =$\frac{9}{7}$ =$1\frac{2}{7}$
