Answer 2

It appears you've provided a system of equations involving the variable "у" (which appears to be the Cyrillic letter "у," likely representing the variable "u" in the Latin alphabet). Let's solve these equations step by step:

1. 19 - у = 16 Subtract 16 from both sides: 19 - у - 16 = 16 - 16 3 - у = 0 Add у to both sides: 3 - у + у = 0 + у 3 = у

2. 20 - у = 9 Subtract 9 from both sides: 20 - у - 9 = 9 - 9 11 - у = 0 Add у to both sides: 11 - у + у = 0 + у 11 = у

3. у + 13 = 17 Subtract 13 from both sides: у + 13 - 13 = 17 - 13 у = 4

4. 19 - у = 12 Subtract 12 from both sides: 19 - у - 12 = 12 - 12 7 - у = 0 Add у to both sides: 7 - у + у = 0 + у 7 = у

Now, we've solved for у (or "u" in the Latin alphabet) in each equation. However, there seems to be a contradiction in these equations. In the first three equations, we found that у = 3, у = 11, and у = 4, respectively. In the fourth equation, we found that у = 7. These values of у do not match, indicating that the system of equations may be inconsistent. Please double-check the equations or provide additional context if needed.
