Question

Решить уравнение 15/42-(х-1/6)=2/7

Answer 1

Ответ:

$\frac{15}{42} - ( x - \frac{1}{6} ) = \frac{2}{7}$

$(x - \frac{1}{6} ) = \frac{2}{7} - \frac{15}{42}$

$(x - \frac{1}{6} ) = \frac{12 - 15}{42}$

$x - \frac{1}{6} = \frac{ - 3}{42}$

$x - \frac{1}{6} = - \frac{1}{14}$

$x = - \frac{1}{14} + \frac{1}{6}$

$x = \frac{ - 3 + 7}{42}$

$x = \frac{4}{42}$
