Question

Решите уравнение : 1) x - 5/23 = 36/92 2) 4/ 3x -11 = 36/63

Answer 1

1)
$x - \frac{5}{23} = \frac{36}{92} \\ x - \frac{5}{2 3} = \frac{9}{23} \\ x = \frac{9}{2 3} + \frac{5}{23} \\ x = \frac{14}{23}$
ответ:
$x = \frac{14}{23}$
2)
$\frac{4}{3x} - 11 = \frac{36}{63} \\ \frac{4}{3x} - 11 = \frac{4}{7} \\ \frac{4}{3x} = \frac{4}{7} + 11 \\ \frac{4}{3x} = \frac{81}{7} \\ 243x = 28 \\ x = \frac{28}{243}$
ответ:
$x = \frac{28}{243}$
