Решите уравнения - 6x = 48 2) 0,8x=-3,2 3) - 1,6x = - 6,4 4) 1/7x = - 3/14 5) - 4/9x = - 1/7 6) - 2 1/4x = 9/16

1) x = 48: (-6)

x = - 8

2) x = - 3,2:0,8

x = - 4

3) x = - 6,4: (-1,6)

x = 4

4) x = - 3/14 : 1/7 = - 3/14*7/1 = - 3/2 = - 1,5

5) x = - - 1/7:4/9 = 1/7*9/4 = 9/28

6) - 2 1/4 = - 9/4

x = - 9/16:9/4 = - 9/16*4/9 = - 4/16 = - 1/4 = - 0,25
