Question

Найдите корни уравнений
1) 5x-3целых 1/2=4целых 2/3
2)уравнение 8x+11целых 2/11=15

Answer 1

1)
$5x - 3 \frac{1}{2} = 4\frac{2}{3} \\ \frac{5}{1} x - \frac{7}{2} = \frac{14}{3} \\ \frac{30}{6} x - \frac{21}{6} = \frac{28}{6} \\ \frac{30}{6} x = \frac{49}{6} \\ x = \frac{49}{6} \times \frac{6}{30} \\ x = \frac{49}{30} \\ x = 1\frac{19}{30}$
