Решите уравнения 1) (2/3x+7/12): 6/11=1 5/6 2) 1 3/8+(5/6x-5/6=2 1/4 нужно !

(2/3 х+7/12):6/11=1 5/6
2/3 х+7/12=11/6*6/11
2/3 х+7/12=1
2/3 х=1-7/12
2/3 х=5/12
х=5/12:2/3=5/12*3/2
х=5/8

1 3/8+(5/6 х-5/6)=2 1/4
5/6 х-5/6=2 1/4-1 3/8=2 2/8-1 3/8
5/6 х-5/6=7/8
5/6 х=7/8+5/6=21/24+20/24
5/6 х=41/24
х=41/24 : 5/6=41/24*6/5
х=41/20=2 1/20
