V obrázku sú dané vektory \( \overrightarrow{a} \), \( \overrightarrow{b} \), \( \overrightarrow{c} \). Vyjadrite vektor \( \overrightarrow{b} \) ako lineárnu kombináciu vektorov \( \overrightarrow{a} \) a \( \overrightarrow{c} \).
\( \overrightarrow{b} = 2\overrightarrow{a} + \overrightarrow{c} \)
\( \overrightarrow{b} = 2\overrightarrow{a} - \overrightarrow{c} \)
\( \overrightarrow{b} = -2\overrightarrow{a} + \overrightarrow{c} \)
\( \overrightarrow{b} = -2\overrightarrow{a} - \overrightarrow{c} \)
