Rovnica s absolútnou hodnotou
Rieš v danej množine rovnicu:
\( \left| {4\ –\ x} \right|\ –\ \left| {2 x + 3} \right| = 7 \) v \( \normalsize\mathbb{R}_0^{+} \)
\( \normalsize K=K_1\mathop{\cup}K_2=\{0\} \)
\( \normalsize K=K_1\mathop{\cup}K_2=\emptyset \)
\( \normalsize K=K_1\mathop{\cup}K_2=\{1, 2\} \)
\( \normalsize K=K_1\mathop{\cup}K_2=\{3\} \)
