Question

e assim ?????
i) x- 1/3 > x/2 + 1/4

Answer 1

$x-\frac{1}{3}\ \textgreater \ \frac{x}{2}+ \frac{1}{4}$

$x-\frac{x}{2}\ \textgreater \ \frac{1}{4} +\frac{1}{3}$

$\frac{2}{2} x-\frac{x}{2}\ \textgreater \ \frac{1.3}{12} +\frac{1.4}{12}$

$\frac{x}{2}\ \textgreater \ \frac{3}{12} +\frac{4}{12}$


$\frac{x}{2}\ \textgreater \ \frac{7}{12}$

multiplicamos os dois lados por dois e cortamos

$2.\frac{x}{2}\ \textgreater \ 2.\frac{7}{12}$

$x\ \textgreater \ \frac{7}{6}$
