Work: Find the solution of equation X/87-15/500-2/44.7 = 0.001905（X+17） .
Question type: Equation
Solution:Original question:
| X | ÷ | 87 | − | 15 | ÷ | 500 | − | 2 | ÷ | 447 10 | = | 381 200000 | ( | X | + | 17 | ) |
| Left side of the equation = | X | × | 1 87 | − | 3 100 | − | 20 447 |
| = | 1 87 | X | − | 3341 44700 |
1 87 | X | − | 3341 44700 | = | 381 200000 | ( | X | + | 17 | ) |
| Right side of the equation = | 381 200000 | X | + | 381 200000 | × | 17 |
| = | 381 200000 | X | + | 6477 200000 |
1 87 | X | − | 3341 44700 | = | 381 200000 | X | + | 6477 200000 |
Transposition :
1 87 | X | − | 381 200000 | X | = | 6477 200000 | + | 3341 44700 |
Combine the items on the left of the equation:
166853 17400000 | X | = | 6477 200000 | + | 3341 44700 |
Combine the items on the right of the equation:
166853 17400000 | X | = | 9577219 89400000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 9577219 89400000 | ÷ | 166853 17400000 |
| = | 9577219 89400000 | × | 17400000 166853 |
| = | 9577219 149 | × | 29 166853 |
We obtained :
| X | = | 277739351 24861097 |
Convert the result to decimal form :
| X | = | 11.171645 |
