Решите уравнение:
1) $\frac{14}{23} - \frac{x}{23} = \frac{6}{23}$;
2) $(x + \frac{12}{49}) - \frac{5}{49} = \frac{33}{49}$.
$\frac{14}{23} - \frac{x}{23} = \frac{6}{23}$
$\frac{x}{23} = \frac{14}{23} - \frac{6}{23}$
$\frac{x}{23} = \frac{8}{23}$
x = 8
Ответ: 8
$(x + \frac{12}{49}) - \frac{5}{49} = \frac{33}{49}$
$x + \frac{12}{49} = \frac{33}{49} + \frac{5}{49}$
$x + \frac{12}{49} = \frac{38}{49}$
$x = \frac{38}{49} - \frac{12}{49}$
$x = \frac{26}{49}$
Ответ: $x = \frac{26}{49}$
