Решите 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) 1/6x = - 2/3; x=-2/3:1/6; x=-4

(3) - 5x=4; x=4: (-5); x=-0,8

(4) - 3/4x = - 9; x=-9: (-3/4); x=12

(5) 7x = - 1,4; x=-1/4: (7); x=-0,2

(6) 2/3x = - 8; x=-8: (2/3); x=-12
