Question

Реши уровненный.
18/30 - х = 4/30 + 6/30
(13/67 + 6/67) - х = 9/67
10/15 + (5/15 - х) = 14/15

___________________

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

Answer 1

1) 18/30-x= 4/30+6/30

18/30-x= 10/30

x= 18/30-10/30

x= 8/30

2) x=13/67+6/67

x=19/67

x=19/67-9/67

x=10/67

3) 5/15-x=14/15-10/15

5/15-x=4/15

x=5/15-4/15

x=1/15

4)8/60+y=41/60+16/60

8/60+y=57/60

y=34/60+8/60

y=42/60

y=57/60-42/60

y=15/60

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

x+26/70=59/70

x=59/70-26/70

x=33/70

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

x+27/46=37/46

x=37/46-27/46

x=10/46
