Answer 1

$\frac{1}{3}x = 12 \\ x = 12 \times 3 \\ x = 36$

$\frac{2}{3} y = 9 \\ y = 9 \times \frac{3}{2} \\ y = 13.5$

$- 4x = \frac{1}{7} \\ x = \frac{1}{7} \div ( - 4) \\ x = - \frac{1}{28}$

$5y = - \frac{5}{8} \\ y = - \frac{5}{8} \div 5 \\ y = - \frac{1}{8}$

$\frac{1}{6}y = \frac{1}{3} \\ y = \frac{1}{3} \times 6 \\ y = 2$

$\frac{2}{7} x = 0 \\ x = 0$

Answer 2

Пошаговое объяснение:

1/3х = 12

х = 12 : 1/3

х = 12 * 3/1

х = 36/1

х = 36

2/3у = 9

у = 9 : 2/3

у = 9 * 3/2

у = 27/2

у = 13 1/2

-4х = 1/7

х = 1/7 : (-4)

х = 1/7 * (-1/4)

х = -1/28

5у = -5/8

у = -5/8 : 5

у = -5/8 * 1/5

у = -5/40

у = -1/8

1/6у = 1/3

у = 1/3 : 1/6

у = 1/3 * 6/1

у = 6/3

у = 2

2/7х = 0

х = 0 : 2/7

х = 0
