Question

8,5 - 2,15х = 3,05х - 9,5.

Answer 1

$8.5 - 2.15x = 3.05x - 9.5$

$850 - 215x = 305x - 950$

$- 215x = 305x - 1800$

$- 520 x= - 1800$

$x = - 1800 \div ( - 520)$

$x = - 45 \div ( - 13)$

$x = \frac{45}{13}$

Answer 2

Ответ:       3 6/13.

Пошаговое объяснение:

8.5 - 2.15х = 3.05х - 9.5.

-2.15x-3.05x = -9.5-8.5;

-5.2x = -18;

x=-18:(-5.2);

x=45/13=3 6/13.
