Реши уравнение икс минус 207 равно 6 седьмых

$x - 207 = \frac{6}{7}$
$x = \frac{6}{7} + 207$
$x = \frac{6}{7} + \frac{207}{1}$
$x = \frac{6}{7} + ( \frac{207}{1}) ^{7}$
$x = \frac{6}{7} + \frac{207 \times 7}{1 \times 7}$
$x = \frac{6}{7} + \frac{1449}{7}$
$x = \frac{6 + 1449}{7}$
$x = \frac{1455}{7} = 207 \: \frac{6}{7}$
$x = 207 \: \frac{6}{7}$
Ответ.
х= $207 \: \frac{6}{7}$

Проверка.

$207 \: \frac{6}{7} - 207 = \frac{6}{7}$
$\frac{1455}{7} - \frac{207}{1} = \frac{6}{7}$
$\frac{1455}{7} - (\frac{207}{1} )^{7} = \frac{6}{7}$
$\frac{1455}{7} - \frac{1449}{7} = \frac{6}{7}$
$\frac{6}{7} = \frac{6}{7}$
