Question

Реши уровненный.
34/60+8/60+y=41/60+16/60
64/70-(x+26/70)=5/70
x+27/46=35/46+2/46

Answer 1

Ответ:

34/60+8/60+у=41/60+16/60

34/60+8/60+у=57/60

8/60+у=57/60-34/60

8/60+у=20/60

У=20/60+8/60

У=28/60

———————————

34/60+8/60+28/60=41/60+16/60

28/60=28/60

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=23/70

———————————

64/70-(23/70+26/70)=5/70

5/70=5/70

х+27/46=35/46+2/46

х+27/46=37/46

х=37/46-27/46

х=10/46

——————————

10/46+27/46=35/46+2/46

10/46=10/47
