Work: Find the solution of equation -0.015 = (X－1847200)/1874200×100％ .
Question type: Equation
Solution:Original question:
| - | 3 200 | = | ( | X | − | 1847200 | ) | ÷ | 1874200 | × | 100 100 |
| Right side of the equation = | ( | X | − | 1847200 | ) | × | 1 1874200 |
| - | 3 200 | = | ( | X | − | 1847200 | ) | × | 1 1874200 |
| Right side of the equation = | X | × | 1 1874200 | − | 1847200 | × | 1 1874200 |
| = | X | × | 1 1874200 | − | 9236 9371 |
| - | 3 200 | = | 1 1874200 | X | − | 9236 9371 |
Transposition :
| - | 1 1874200 | X | = | - | 9236 9371 | + | 3 200 |
Combine the items on the right of the equation:
| - | 1 1874200 | X | = | - | 1819087 1874200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1819087 1874200 | = | 1 1874200 | 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 :
1 1874200 | X | = | 1819087 1874200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1819087 1874200 | ÷ | 1 1874200 |
| = | 1819087 1874200 | × | 1874200 |
| = | 1819087 9371 | × | 9371 |
We obtained :
| X | = | 17046664277 9371 |
