Work: Find the solution of equation (y-2)/2019+y/2020+(y+2/2021) = 6 .
Question type: Equation
Solution:Original question:
| ( | y | − | 2 | ) | ÷ | 2019 | + | y | ÷ | 2020 | + | ( | y | + | 2 | ÷ | 2021 | ) | = | 6 |
| Left side of the equation = | y | × | 1 2019 | − | 2 | × | 1 2019 | + | 1 2020 | y | + | ( | y | + | 2 | ÷ | 2021 | ) |
| = | y | × | 1 2019 | − | 2 2019 | + | 1 2020 | y | + | ( | y | + | 2 | ÷ | 2021 | ) |
| = | 4039 4078380 | y | − | 2 2019 | + | ( | y | + | 2 | ÷ | 2021 | ) |
| = | 4039 4078380 | y | − | 2 2019 | + | y | + | 2 | ÷ | 2021 |
| = | 4039 4078380 | y | − | 2 2019 | + | y | + | 2 2021 |
| = | 4082419 4078380 | y | − | 4 4080399 |
4082419 4078380 | y | − | 4 4080399 | = | 6 |
Transposition :
4082419 4078380 | y | = | 6 | + | 4 4080399 |
Combine the items on the right of the equation:
4082419 4078380 | y | = | 24482398 4080399 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 24482398 4080399 | ÷ | 4082419 4078380 |
| = | 24482398 4080399 | × | 4078380 4082419 |
| = | 24482398 2021 | × | 2020 4082419 |
We obtained :
| y | = | 49454443960 8250568799 |
