Решите уравнение: 1) 2 2/11x - 5/16 = 1 3/4 2)4 2/9x + 3 5/14 = 6 11/21 3)11/18 - 14/27x...

1) $\frac{22}{11x} - \frac{5}{16} = \frac{13}{4}$
$\frac{22}{11x} - \frac{5}{16} = \frac{13}{4} , x \neq 0$
$\frac{2}{x} - \frac{5}{16} = \frac{13}{4}$
$\frac{2}{x} = \frac{13}{4} + \frac{5}{16}$
$\frac{2}{x} = \frac{57}{16}$
$32=57x$
$57x=32$
$x= \frac{32}{57} , x \neq 0$
$x= \frac{32}{57}$
Альтернативный вид
x≈0.561404

2)
$\frac{42}{9x} + \frac{35}{14} = \frac{611}{21}$
$\frac{42}{9x} + \frac{35}{14} = \frac{611}{21} , x \neq 0$
$\frac{14}{3x} + \frac{5}{2} = \frac{611}{21}$
$\frac{14}{3x} = \frac{611}{21} - \frac{5}{2}$
$\frac{14}{3x} = \frac{1117}{42}$
$588=3351x$
$3351x=588$
$x= \frac{196}{1117} , x \neq 0$
$x= \frac{196}{1117}$
Альтернативный вид
x≈0.17547
