Question

- 5(-5 + 3x) - 1 = 9x + 5.6;

Answer 1

- 5(-5 + 3x) - 1 = 9x + 5.6

25 - 15х - 1 = 9х + 5.6

24 - 15х= 9х + 5.6

24- 15х - 9х = 5.6

-15х - 9х = 5.6 - 24

-24х= -18.4

х= 23/30

Answer 2

Объяснение:

$- 5( - 5 + 3x) - 1 = 9x + 5.6 \\ 25 - 15x - 1 = 9 x + 5.6 \\ 24 - 15x = 9x + 5.6 \\ 24 - 15x - 9x = 5.6 \\ 24 - 24x = 5.6 \\ - 24 = 5.6 - 24 \\ - 24x = - 18.4 \\ x = - 18.4 \div ( - 24) \\ x = \frac{23}{30}$
