срочно нужна помощь!

Answer 1

Ответ:

-4 + x = 12

x = 12 + 4

x = 16

-4 - x = -12

-x = -12 + 4

-x = -8

x = 8

4x = -12

x = -12/4

x = -3

5x = 12

x = 12/5

-4 ÷ 6 = -2/3

x ÷ (-4) = -12

x = -12 × (-4)

x = 48

0.5x = -0.3 × 15

0.5x = -4.5

x = -4.5 ÷ 0.5

x = -9

16 = 16x

x = 16 ÷ 16

x = 1

12(x + 5) = -24

12x + 60 = -24

12x = -84

x = -7

3(6 - x) - 2(x - 5) = 63

18 - 3x - 2x + 10 = 63

28 - 5x = 63

-5x = 35

x = -7
