Answer 1

Ответ:

18/30-x=4/30+6/30

18/30-x=10/30

x=18/30-10/30

x=8/30

18/30-8/30=4/30+6/30

(13/67+6/67)-x=9/67

19/67-x=9/67

x=19/67-9/67

x=10/67

(13/67+6/67)-10/67=9/67

10/15+(5/15-x)=14/15

5/15-x=14/15-10/15

5/15-x=4/15

x=5/15-4/15

x=1/15

10/15+(5/15-1/15)=14/15

34/60+8/60+y=41/60+16/60

42/60+y=57/60

y=57/60-42/60

y=15/60

64/70-(x+26/70)=5/70

x+26/70=64-5/70

x+26/70=59/70

x=59/70-26/70

x=33/70

x+27/46=35/46+2/46

x+27/46=37/46

x=37/46-27/46

x=10/46
