Work: Find the solution of equation (191199+4200+X)*105% = 207825 .
Question type: Equation
Solution:Original question:
| ( | 191199 | + | 4200 | + | X | ) | × | 105 100 | = | 207825 |
| Left side of the equation = | 191199 | × | 105 100 | + | 4200 | × | 105 100 | + | X | × | 105 100 |
| = | 4015179 20 | + | 4410 | + | X | × | 105 100 |
| = | 4103379 20 | + | 105 100 | X |
4103379 20 | + | 105 100 | X | = | 207825 |
Transposition :
105 100 | X | = | 207825 | − | 4103379 20 |
Combine the items on the right of the equation:
105 100 | X | = | 53121 20 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 53121 20 | ÷ | 105 100 |
| = | 53121 20 | × | 100 105 |
| = | 17707 | × | 5 35 |
We obtained :
| X | = | 88535 35 |
By reducing fraction, we can get:
| X | = | 17707 7 |
Convert the result to decimal form :
| X | = | 2529.571429 |
