Work: Find the solution of equation 3997116 = X-X*12%/1.05*0.05 .
Question type: Equation
Solution:Original question:
| 3997116 | = | X | − | X | × | 12 100 | ÷ | 21 20 | × | 1 20 |
| Right side of the equation = | X | − | X | × | 1 175 |
| = | 174 175 | X |
| 3997116 | = | 174 175 | X |
Transposition :
| - | 174 175 | X | = | - | 3997116 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 3997116 | = | 174 175 | X |
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 :
174 175 | X | = | 3997116 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 3997116 | ÷ | 174 175 |
| = | 3997116 | × | 175 174 |
| = | 666186 | × | 175 29 |
We obtained :
| X | = | 116582550 29 |
Convert the result to decimal form :
| X | = | 4020087.931034 |
