Answer 1

$\displaystyle 1)|\frac{1}{x}|=2,5,z\neq 0\\ \\\frac{|1|}{|z|}=\frac{2}{5}\\ \\\frac{1}{|z|}=\frac{2}{5}\\ \\5=2*|z|\\ 2*|z|=5\\ \\|z|=\frac{5}{2}\\ \\z=б\frac{5}{2}=б2,5\\ \\2)|\frac{3}{y}|=\frac{5}{6},y\neq 0\\ \\\frac{|3|}{|y|}=\frac{5}{6}\\ \\\frac{3}{|y|}=\frac{5}{6}\\ \\18=5*|y|\\ 5*|y|=18\\ \\|y|=\frac{18}{5}\\ \\y=б\frac{18}{5}=б3,6$
