Answer
$1\frac{2}{7}$
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+$\frac{6}{7}$+$\frac{3}{7}$
=$\frac{9}{7}$
=$1\frac{2}{7}$
