Explicație pas cu pas:

Answer 2

$C=\left\{x\:\in\:\mathbb{N}\:|\:2x-3 \leqslant 10\right\}$

$2x - 3 \leqslant 10$

$2x \leqslant 10 + 3$

$2x \leqslant 13$

$x \leqslant \frac{13}{2}$

$x \leqslant 6.5$

$x \: \in \: \mathbb{N} = > x \: \in \: \left\{0,1,2,3,4,5,6\right\}$

$= > C=\left\{0,1,2,3,4,5,6\right\}$
