[ 1/1 Equation]
Work: Find the solution of equation （y-19974.6-6.83-35）*0.25+y*0.0005+35+21193 = y .
Question type: Equation
Solution:Original question:
| ( | y | − | 99873 5 | − | 683 100 | − | 35 | ) | × | 1 4 | + | y | × | 1 2000 | + | 35 | + | 21193 | = | y |
| Left side of the equation = | ( | y | − | 99873 5 | − | 683 100 | − | 35 | ) | × | 1 4 | + | 1 2000 | y | + | 21228 |
| ( | y | − | 99873 5 | − | 683 100 | − | 35 | ) | × | 1 4 | + | 1 2000 | y | + | 21228 | = | y |
| Left side of the equation = | y | × | 1 4 | − | 99873 5 | × | 1 4 | − | 683 100 | × | 1 4 | − | 35 | × | 1 4 | + | 1 2000 | y | + | 21228 |
| = | y | × | 1 4 | − | 99873 20 | − | 683 400 | − | 35 4 | + | 1 2000 | y | + | 21228 |
| = | 501 2000 | y | + | 6489557 400 |
501 2000 | y | + | 6489557 400 | = | y |
Transposition :
501 2000 | y | − | y | = | - | 6489557 400 |
Combine the items on the left of the equation:
| - | 1499 2000 | y | = | - | 6489557 400 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
6489557 400 | = | 1499 2000 | 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 :
1499 2000 | y | = | 6489557 400 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 6489557 400 | ÷ | 1499 2000 |
| = | 6489557 400 | × | 2000 1499 |
| = | 6489557 | × | 5 1499 |
We obtained :
| y | = | 32447785 1499 |
Convert the result to decimal form :
| y | = | 21646.287525 |
