( уравнения с дробями )

Answer 1

1) ( 3 5/6 + a) - 2 16 = 5
3  5/6+а=5+2  1/6
3 5/6+а=7 1/6
а=7 1/6-3 5/6
а=43/6-23/6
а=20/6
а=10/3=3  1/3
2) 8 613 - ( b + 913) = 4 213
b+9/13=8 6/13-4 2/13
b+9/13=110/13-54/13
b+9/13=56/13
b=56/13-9/13
b=47/13=3 8/13

Answer 2

1) ( 3 5/6 + a) - 2 16 = 5
23/6+а-13/6=5
23+6а-13=30
6а=30+13-23=20
а=10/3=3 1/3
а=3 1/3

2) 8 613 - ( b + 913) = 4 213
110/13-b-9/13=54/13
110-13b-9=54
-13b=54-110+9
-13b=-47
b=47/13=3 8/13
b= 3 8/13
