Answer 1

$- 12 \div 5x = - 6 \\ 5x = - 12 \div - 6 \\ 5x = 2 \\ x = \frac{2}{5} \\ x = 0.4$

$- 1 \frac{2}{3} x = 1 \frac{4}{5} \\ x = 1 \frac{4}{5} \div ( - 1 \frac{2}{3} ) \\ x = - \frac{9 \times 3}{5 \times 5} \\ x = - \frac{27}{25} \\ x = - 1 \frac{2}{25} \\ x = - 0.08$

$6x \div ( - 24) = 0 \\ x = 0$

$\frac{2}{7} x = - 1 \\ x = - 1 \div \frac{2}{7} \\ x = - \frac{7}{2} \\ x = - 3 \frac{1}{2} \\ x = - 3.5$

Answer 2

Пошаговое объяснение:

-12 : 5х = -6

5х = -12 : (-6)

5х = 2

х = 2 : 5

х = 2/5 или 0,4

-1 2/3х = 1 4/5

-5/3х = 9/5

х = 9/5 : (-5/3)

х = 9/5 * (-3/5)

х = -27/25

х = -1 2/25

6х : (-24) = 0

6х = 0 * (-24)

6х = 0

х = 0 : 6

х = 0

2/7х = 1

х = 1 : 2/7

х = 1 * 7/2

х = 7/2

х = 3,5 или 3 1/2
