Answer 1

18/30-х=4/30+6/30

х=10/30

х=18/30-10/30

х=8/30

_________

18/30-8/30=10/30

34/60+8/60+у=41/60+16/60

у=41/60+16/60

у=57/60

у=57/60-(34/60+8/60)

у=57/60-42/60

у=42/60

(13/67+6/67)-х=9/67

х=13/67+6/67

х=19/67

х=19/67-9/67

х=10/67

10/15+(5/15-х)=14/15

х=14/15-10/15

х=4/15

х=5/15-4/15

х=1/15

64/70-(х+26/70)=5/70

х+26/70=64/70-5/70

х+26/70=59/70

х=59/70-26/70

х=33/70

х+27/46=35/46+2/46

х+27/46=37/46

х=37/46-27/46

х=10/46
