Work: Find the solution of equation （12812*3.98%+x）/（12812-x） = 10% .
Question type: Equation
Solution:Original question:
| ( | 12812 | × | 199 5000 | + | x | ) | ÷ | ( | 12812 | − | x | ) | = | 10 100 |
| Multiply both sides of the equation by: | ( | 12812 | − | x | ) |
| ( | 12812 | × | 199 5000 | + | x | ) | = | 10 100 | ( | 12812 | − | x | ) |
| 12812 | × | 199 5000 | + | x | = | 10 100 | ( | 12812 | − | x | ) |
| 12812 | × | 199 5000 | + | x | = | 10 100 | × | 12812 | − | 10 100 | x |
637397 1250 | + | x | = | 6406 5 | − | 10 100 | x |
Transposition :
| x | + | 10 100 | x | = | 6406 5 | − | 637397 1250 |
Combine the items on the left of the equation:
11 10 | x | = | 6406 5 | − | 637397 1250 |
Combine the items on the right of the equation:
11 10 | x | = | 964103 1250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 964103 1250 | ÷ | 11 10 |
| = | 964103 1250 | × | 10 11 |
| = | 964103 125 | × | 1 11 |
We obtained :
| x | = | 964103 1375 |
Convert the result to decimal form :
| x | = | 701.165818 |
