Пошаговое объяснение:
18/30-х=4/30+6/30
Х=18/30-4/30-6/30
Х=8/30=4/15
(13/67+6/67)-х=9/67
19/67-х=9/67
Х=19/67-9/67
Х=10/67
10/15+(5/15-х)=14/15
Х=10/15+5/15-14/15
Х=1/15
34/60+8/60+у=41/60+16/60
У=41/60+16/60-8/60-34/60
У=15/60=1/4
64/70-(х+26/70)=5/70
64/70-х-26/70=5/70
Х=64/70-26/70-5/70
Х=33/70
х+27/46=35/46+2/46
Х+27/46=37/46
Х=37/46-27/46
Х=10/46=5/23
