Work: Find the solution of equation 20/102+10/44.7+X/127.5+（68.4-X）/1000 = 0.74 .
Question type: Equation
Solution:Original question:
| 20 | ÷ | 102 | + | 10 | ÷ | 447 10 | + | X | ÷ | 255 2 | + | ( | 342 5 | − | X | ) | ÷ | 1000 | = | 37 50 |
| Left side of the equation = | 10 51 | + | 100 447 | + | X | × | 2 255 | + | ( | 342 5 | − | X | ) | × | 1 1000 |
| = | 3190 7599 | + | 2 255 | X | + | ( | 342 5 | − | X | ) | × | 1 1000 |
3190 7599 | + | 2 255 | X | + | ( | 342 5 | − | X | ) | × | 1 1000 | = | 37 50 |
| Left side of the equation = | 3190 7599 | + | 2 255 | X | + | 342 5 | × | 1 1000 | − | X | × | 1 1000 |
| = | 3190 7599 | + | 2 255 | X | + | 171 2500 | − | X | × | 1 1000 |
| = | 9274429 18997500 | + | 349 51000 | X |
9274429 18997500 | + | 349 51000 | X | = | 37 50 |
Transposition :
349 51000 | X | = | 37 50 | − | 9274429 18997500 |
Combine the items on the right of the equation:
349 51000 | X | = | 4783721 18997500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4783721 18997500 | ÷ | 349 51000 |
| = | 4783721 18997500 | × | 51000 349 |
| = | 4783721 745 | × | 2 349 |
We obtained :
| X | = | 9567442 260005 |
Convert the result to decimal form :
| X | = | 36.797146 |
