[tex] \frac{a}{b} = \frac{2}{6} - > 6a = 2b - > a = \frac{ 2b}{6} [/tex]
[tex] \binom{2b}{6} - b \: = 64218[/tex]
*aducem la acelasi numitor si aplificam pe b cu 6 si 64218 tot cu 6*
[tex]2b - 6b = 64218 \times 6[/tex]
[tex] - 4b = 64218 \times 6 \\ \\ b = - \frac{64218 \times 6}{4} \\ b = - \frac{385.308}{4} \\ b = - 96.327[/tex]
[tex]a = \frac{2 \times ( - 96.327)}{6} \\ b \\ a = \frac{ - 192.654}{6} \\ a = - 32.109[/tex]
