Work: Find the solution of equation x-3/2019+x-2/2020+x-1/2021 = 3 .
Question type: Equation
Solution:Original question:
| x | − | 3 | ÷ | 2019 | + | x | − | 2 | ÷ | 2020 | + | x | − | 1 | ÷ | 2021 | = | 3 |
| Left side of the equation = | x | − | 1 673 | + | x | − | 1 1010 | + | x | − | 1 2021 |
| = | 3 | x | − | 4081073 1373734330 |
| 3 | x | − | 4081073 1373734330 | = | 3 |
Transposition :
| 3 | x | = | 3 | + | 4081073 1373734330 |
Combine the items on the right of the equation:
| 3 | x | = | 4125284063 1373734330 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4125284063 1373734330 | ÷ | 3 |
| = | 4125284063 1373734330 | × | 1 3 |
We obtained :
| x | = | 4125284063 4121202990 |
Convert the result to decimal form :
| x | = | 1.00099 |
