Question

3 целых 4/9 + ( 8 целых -d)= 6 целых 5/9
( уравнения с дробями )

Answer 1

3  4/9 + ( 8  -d)=  6  5/9
31/9 + 8 - d = 59/9
-d = 59/9 -31/9 -8
-d = 28/9 -8
-d = 28/9 -72/9 
d = 44/9 = 4 ц  8/9

Answer 2

3  4/9 + ( 8  -d)=  6  5/9
31/9 + 8 - d = 59/9
-d = 59/9 -31/9 -8
-d = 28/9 -8
-d = 28/9 -72/9 
d = 44/9 = 4 ц  8/9
