Work: Find the solution of equation 451X-451*1.439 = 315X-315*1.434 .
Question type: Equation
Solution:Original question:
| 451 | X | − | 451 | × | 1439 1000 | = | 315 | X | − | 315 | × | 717 500 |
| Left side of the equation = | 451 | X | − | 648989 1000 |
| 451 | X | − | 648989 1000 | = | 315 | X | − | 315 | × | 717 500 |
| Right side of the equation = | 315 | X | − | 45171 100 |
| 451 | X | − | 648989 1000 | = | 315 | X | − | 45171 100 |
Transposition :
| 451 | X | − | 315 | X | = | - | 45171 100 | + | 648989 1000 |
Combine the items on the left of the equation:
| 136 | X | = | - | 45171 100 | + | 648989 1000 |
Combine the items on the right of the equation:
| 136 | X | = | 197279 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 197279 1000 | ÷ | 136 |
| = | 197279 1000 | × | 1 136 |
We obtained :
| X | = | 197279 136000 |
Convert the result to decimal form :
| X | = | 1.450581 |
