Реши уравнение 5x-1/12-3x+2/8=1 и выполните проверку

Answer 1

$5x- \frac{1}{12}-3x+ \frac{2}{8}=1$

$2x- \frac{2}{24} + \frac{6}{24} =1$

$2x+ \frac{4}{24} =1$

$2x=1- \frac{4}{24}$

$2x= \frac{20}{24}$

$x= \frac{20}{24}* \frac{1}{2}$

$x= \frac{5}{12}$

Проверка:

$5* \frac{5}{12} - \frac{1}{12} -3* \frac{5}{12} + \frac{2}{8} =1$

$\frac{25}{12} - \frac{1}{12} - \frac{15}{12} + \frac{2}{8}=1$

$\frac{9}{12}+ \frac{2}{8} =1$

$\frac{18}{24} + \frac{6}{24}=1$

$\frac{24}{24}=1$
