Решите уравнение 0,6x-1,8x=36

1. 6:х=36:30 6:х=1.2 х=6:1.2 х=5 2. 12:7=3:х 1,71428571=3:х х=1,75 3. 4,9:0,35=х:35 14=х:35 х=14*35 х=490 4. х/21=9/14 14*х=189 х=13,5 5. х/16=3/8 8*х=48 х=6 6.108/90=42/д 108*д=3780 д=3780:108 д=35

0,6х - 1,8х = 36-1,2х = 36х = 36 : (-1.2)х = -30

0,6x-1,8x=36-1,2x=36x=-30
