Dokáž nasledujúce tvrdenie sporom:
\( \large\frac{x}{10}+6x-1,4\lt\frac35+6,1x \)
\( \large \Large \frac{x}{10}\large + 6x- 1,4 \neq \Large \frac{3}{5}\large + 6,1x\rightarrow -14 \neq 6 \) (t. j. spor)
\( \large \Large \frac{x}{10}\large + 6x- 1,4 \leq \Large \frac{3}{5}\large + 6,1x\rightarrow -14 \leq 6 \) (t. j. spor)
\( \large \Large \frac{x}{10}\large + 6x- 1,4 \geq \Large \frac{3}{5}\large + 6,1x\rightarrow -14 \geq 6 \) (t. j. spor)
\( \large \Large \frac{x}{10}\large + 6x- 1,4 \gt \Large \frac{3}{5}\large + 6,1x\rightarrow -14 \gt 6 \) (t. j. spor)
