Question

5 4/15-3 4/7x=4 2/3
Уравнение

Answer 1

$5 \frac{4}{15} - 3 \frac{4}{7}x = 4 \frac{2}{3}$

$- 3 \frac{4}{7} x = 4 \frac{2}{3} - 5 \frac{4}{15}$

$- 3 \frac{4}{7} x = - \frac{3}{5}$

$x = - \frac{3}{5} \div ( - 3 \frac{4}{7} )$

$x = \frac{21}{125}$

Ответ :

$\frac{21}{125}$

Answer 2

-3 4/7х=4 2/3-5 4/15

-3 4/7х= 4/3

-х=-7/9
