Answer 1

Resposta:

$\frac{p - 5}{6} + \frac{2 - p}{3} - \frac{p - 6}{5} = - 3 \\ \frac{5(p - 5)}{30} + \frac{10(2 - p)}{30} - \frac{6(p - 6)}{30} = - 3 \\ \frac{5p - 25}{30} + \frac{20 - 10p}{30} - \frac{6p - 36}{30} = - 3 \\ \frac{5p - 10p - 6p}{30} + \frac{ - 25 + 20 + 36}{30} = - 3 \\ \frac{ - 11p}{30} + \frac{31}{30} = - 3 \\ - 11p + 31 = - 3 \times 30 \\ - 11p = - 90 - 31 \\ - 11p = - 121 \\ p = - 121 \div - 11 \\ p = 11$
