Question

Решите уравнение
(x-3целых1/3)x14=26

Answer 1

$(x-3 frac{1}{3} )*14=26 \ x-3 frac{1}{3} = frac{26}{14} \ x-3 frac{1}{3}= frac{13}{7} \ x=3 frac{1}{3}+ frac{13}{7} \ x=frac{10}{3}+ frac{13}{7} \ x=frac{70}{21}+ frac{39}{21} \ x= frac{109}{21} \ x=5 frac{4}{21}$

Answer 2

$x-3 frac{1}{3} *14=26 \ x-3 frac{1}{3} = frac{26}{14} \ x-3 frac{1}{3} = frac{13}{7} \ x-3 frac{1}{3} =1 frac{6}{7} \ 1 frac{6}{7} +3 frac{1}{3} =1 frac{18}{21} +3 frac{7}{21} =4 frac{25}{21} =5 frac{4}{21} \ \ x=5 frac{4}{21}$
