Question

Solve the inequality -5/7 - 6/7z < -2/7

Answer 1

$-\cfrac{5}{7}-\cfrac{6}{7}z~~ < ~~-\cfrac{2}{7}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{7}}{-5-6z~~ < ~~-2} \\\\\\ \stackrel{\textit{dividing by a negative value}}{-6z~}~\cfrac{3}{-6}}\implies \boxed{z~>-\cfrac{1}{2}}$
