Answer 1

$-x+ \frac{3}{5} \geq 0$

$-x \geq 0- \frac{3}{5} -x \geq - \frac{3}{5}$

multiplicamos por -1 obtendo a resposta abaixo
$x \leq \frac{3}{5}$

Letra B
$-2x+ \frac{3}{6} \ \textless \ 0$

$-2x\ \textless \ - \frac{3}{6}$
multiplicamos por -1
$2x\ \textgreater \ \frac{3}{6}$

$x\ \textgreater \ \frac{3}{6} /2$

$x \ \textgreater \ \frac{3}{6} * \frac{1}{2}$

$x \ \textgreater \ \frac{3}{12}$

$x \ \textgreater \ \frac{1}{4}$

letra C
$- \frac{2}{3} x- \frac{4}{5} \leq 0$

$- \frac{2}{3}x \leq \frac{4}{5}$

multiplicamos por -1

$\frac{2}{3}x \geq -\frac{4}{5}$

$x \geq (-\frac{4}{5})/\frac{2}{3}$

$x \geq (-\frac{4}{5})*\frac{3}{2}$

$x \geq \frac{12}{10} x \geq \frac{6}{5}$
