1)2/3x-1/2x 2)1/4x+1/3x 3)-7/12y-5/6y 4)8/15y-2/5y 5)5/9m+2/3m 6)3/4m-1/6m решите пж

1). 2\3x-1\2x = 4\6x - 3\6x = 1\6x 

2). 1\4x+1\3x = 3\12x+4\12x = 7\12x

3). -7\12y-5\6y = -7\12y-10\12y = -17\12y = -1 5\12y

4). 8\15y-2\5y = 8\15y - 6\15y = 2\15y

5). 5\9m+2\3m = 5\9m+6\9m = 11\9m = 1 2\9m

3\4m - 1\6m = 9\12m - 2\12m = 7\12m
