Work: Find the solution of equation 450X-310.02-240X-（450X） = 0 .
Question type: Equation
Solution:Original question:
| 450 | X | − | 15501 50 | − | 240 | X | − | ( | 450 | X | ) | = | 0 |
| Left side of the equation = | 210 | X | − | 15501 50 | − | ( | 450 | X | ) |
| 210 | X | − | 15501 50 | − | ( | 450 | X | ) | = | 0 |
| Left side of the equation = | 210 | X | − | 15501 50 | − | 450 | X |
| = | - | 240 | X | − | 15501 50 |
| - | 240 | X | − | 15501 50 | = | 0 |
Transposition :
| - | 240 | X | = | 0 | + | 15501 50 |
Combine the items on the right of the equation:
| - | 240 | X | = | 15501 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 15501 50 | = | 240 | 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 :
| 240 | X | = | - | 15501 50 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 15501 50 | ÷ | 240 |
| = | - | 15501 50 | × | 1 240 |
| = | - | 5167 50 | × | 1 80 |
We obtained :
| X | = | - | 5167 4000 |
Convert the result to decimal form :
| X | = | - 1.29175 |
