У-3,2+2y-4,6-5y = -3.2+2y-4.6-5y
У-3.2 is equal to -3.2y
-4.6-5y is equal to -4.6-5y

Therefore, the expression becomes:
-3.2y + 2y - 4.6 - 5y = -6.2y - 4.6 - 5y = -11.2y - 4.6

So, У-3,2+2у-4,6-5у simplifies to -11.2y - 4.6

0,2d-2/3-2d+5/9 = 0.2d - (2/3) - 2d + (5/9)
0.2d is equal to 0.2d
-2/3 is equal to -0.67
-2d is equal to -2d
5/9 is equal to 0.56 recurring

Therefore, the expression becomes:
0.2d - 0.67 - 2d + 0.56 recurring = -1.8d - 0.67 + 0.56 recurring = -1.8d - 0.11

So, 0,2д-2/3-2д+5/9 simplifies to -1.8d - 0.11
