Question

Уравнение:
14 - (5х-6 целых 1/7)=6/7 * (5 - 12х)

Answer 1

$14 - (5x-6 \frac{1}{7} )= \frac{6}{7} * (5 - 12x ) \\ 14-5x+6 \frac{1}{7}= \frac{30}{7}- \frac{72}{7}x \\ -5 x+ 10\frac{2}{7}x=4\frac{2}{7}-14-6 \frac{1}{7} \\ 5 \frac{2}{7}x=-16 \frac{1}{7} \\ x=- \frac{113*7}{7*37} \\ x= -3 \frac{2}{7}$
