Решите уравнение:

1) 3 х=-12

2) 1/6 х=-2

3) - 5 х=4

4) - 3/4 х=-9

5) 7 х=-1,4

6) 2/3 х=-8

1) 3x = - 12

x = - 12 : 3

x = - 4

2) 1/6x = - 2/3

x = - 2/3 : 1/6

x = - 4

3) - 5x = 4

x = 4 : (-5)

x = - 4/5

4) - 3/4x = - 9

x = - 9 : (-3/4)

x = 12

5) 7x = - 1.4

x = - 1.4 : 7

x = - 2

6) 2/3x = - 8

x = - 8 : 2/3

x = - 12
