Work: Find the solution of equation 1/2022y+1/2022+2022 = 2y-2019 .
Question type: Equation
Solution:Original question:
| 1 | ÷ | 2022 | × | y | + | 1 | ÷ | 2022 | + | 2022 | = | 2 | y | − | 2019 |
| Left side of the equation = | 1 2022 | y | + | 1 2022 | + | 2022 |
| = | 1 2022 | y | + | 4088485 2022 |
1 2022 | y | + | 4088485 2022 | = | 2 | y | − | 2019 |
Transposition :
1 2022 | y | − | 2 | y | = | - | 2019 | − | 4088485 2022 |
Combine the items on the left of the equation:
| - | 4043 2022 | y | = | - | 2019 | − | 4088485 2022 |
Combine the items on the right of the equation:
| - | 4043 2022 | y | = | - | 8170903 2022 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
8170903 2022 | = | 4043 2022 | y |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
4043 2022 | y | = | 8170903 2022 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 8170903 2022 | ÷ | 4043 2022 |
| = | 8170903 2022 | × | 2022 4043 |
| = | 628531 337 | × | 337 311 |
We obtained :
| y | = | 211814947 104807 |
By reducing fraction, we can get:
| y | = | 2021 |
