Надо решить уравнение 1. 3x=-12 2.1/6x=-2/3 3.-5x=4 4.-3/4x=-9 5. 7x=-1.4 6.2/3x=-8

1) 3x = - 12

x = - 12 / 3

x = - 4

2) 2/6x = - 2/3

x = - 2/3 : 2/6

x = - 2/3 · 6/2

x = - 6/3

x = - 2

3) - 5x = 4

x = - 4/5

x = - 8/10

x = - 0,8

4) - 3/4x = - 9

x = - 9 : (-3/4)

x = 9 · 4/3

x = 12

5) 7x = - 1,4

x = - 14/10 : 7

x = - 14/10 · 1/7

x = - 0,2

6) 2/3x = - 8

x = - 8 : 2/3

x = - 8 · 3/2

x = - 12

3x=-12

х=-4

1/6x=-2/3

х=-2/3:1/6

х=-2/3*6/1

х=-12/3

х=-4

5x=4

х=4/5

-3/4x=-9

х=-9:-3/4

х=-9*-4/3

х=36/3

х=12

7x=-1.4

х=-1.4/7

2/3x=-8

х=-8:2/3

х=-8*3/2

х=-24/2

х=-12
