Work: Find the solution of equation （X-6007.5）*0.03 = X-9720.07 .
Question type: Equation
Solution:Original question:
| ( | X | − | 12015 2 | ) | × | 3 100 | = | X | − | 972007 100 |
| Left side of the equation = | X | × | 3 100 | − | 12015 2 | × | 3 100 |
| = | X | × | 3 100 | − | 7209 40 |
3 100 | X | − | 7209 40 | = | X | − | 972007 100 |
Transposition :
3 100 | X | − | X | = | - | 972007 100 | + | 7209 40 |
Combine the items on the left of the equation:
| - | 97 100 | X | = | - | 972007 100 | + | 7209 40 |
Combine the items on the right of the equation:
| - | 97 100 | X | = | - | 1907969 200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1907969 200 | = | 97 100 | 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 :
97 100 | X | = | 1907969 200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1907969 200 | ÷ | 97 100 |
| = | 1907969 200 | × | 100 97 |
| = | 1907969 2 | × | 1 97 |
We obtained :
| X | = | 1907969 194 |
Convert the result to decimal form :
| X | = | 9834.891753 |
