Work: Find the solution of equation X/126-3/44.7-2/45-(90-X)/500 = 0.238 .
Question type: Equation
Solution:Original question:
| X | ÷ | 126 | − | 3 | ÷ | 447 10 | − | 2 | ÷ | 45 | − | ( | 90 | − | X | ) | ÷ | 500 | = | 119 500 |
| Left side of the equation = | X | × | 1 126 | − | 10 149 | − | 2 45 | − | ( | 90 | − | X | ) | × | 1 500 |
| = | 1 126 | X | − | 748 6705 | − | ( | 90 | − | X | ) | × | 1 500 |
1 126 | X | − | 748 6705 | − | ( | 90 | − | X | ) | × | 1 500 | = | 119 500 |
| Left side of the equation = | 1 126 | X | − | 748 6705 | − | 90 | × | 1 500 | + | X | × | 1 500 |
| = | 1 126 | X | − | 748 6705 | − | 9 50 | + | X | × | 1 500 |
| = | 313 31500 | X | − | 19549 67050 |
313 31500 | X | − | 19549 67050 | = | 119 500 |
Transposition :
313 31500 | X | = | 119 500 | + | 19549 67050 |
Combine the items on the right of the equation:
313 31500 | X | = | 355069 670500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 355069 670500 | ÷ | 313 31500 |
| = | 355069 670500 | × | 31500 313 |
| = | 355069 149 | × | 7 313 |
We obtained :
| X | = | 2485483 46637 |
Convert the result to decimal form :
| X | = | 53.29423 |
