Решите уравнение. 1)х+4 3/4=5 1/7+1/2 2)(15 1/5-х)+2 3/4=6 1/6 3)2 3/4-(5 5/6-у)=1 2/3 4)(у-5 5/6)-1 3/8=3/4 5)х-2 2/3=8 4/5-6 19/20 6) (7 7/8+)-1 5/6= 9 11/16

1) х+4 3/4=5 1/7+1/2
х+19/4-36/7-1/2=0
х+(133-144-14)/28=0
х-25/28=0
х= 25/28
2)(15 1/5-х)+2 3/4=6 1/6
76/5-х+11/4-37/6=0
(912+165-370)/60-х=0
707/60-х=0
х=707/60=11 47/60
3) 2 3/4-(5 5/6-у)=1 2/3
11/4-35/6+у-5/3=0
(33-70-20)/ 12+у=0
-57/12+у=0
у=57/12=4 9/12=4 3/4
4) (у-5 5/6)-1 3/8=3/4
у-35/6-11/8-3/4=0
у-(140-33-18)/24=0
у-89/24=0
у=89/24=3 11/24
