Explicație pas cu pas:
32.
a)
[tex]-26 < -\overline {2x} \\ 26 > \overline {2x} \iff \overline {2x} < 26 \\ x \in \{0;1;2;3;4;5\}[/tex]
b)
[tex]-\overline {1x5} \geqslant - 134 \\ \overline {1x5} \leqslant 134 \\ x \in \{0;1;2\}[/tex]
c)
[tex]- 542 \leqslant -\overline {x52} \\542 \geqslant \overline {x52} \iff \overline {x52} \leqslant 542 \\ x \in \{1;2;3;4\}[/tex]
