Question type: Equation
Solution:Original question:
259 10 | × | 31 100 | × | 21 25 | × | 67 10 | − | 19 | − | 259 10 | = | x | × | 31 100 | × | 21 25 | × | 67 10 | − | 16 | − | 259 10 | − | 1 5 |
| Left side of the equation = | 11296803 250000 | − | 19 | − | 259 10 |
| = | 71803 250000 |
71803 250000 | = | x | × | 31 100 | × | 21 25 | × | 67 10 | − | 16 | − | 259 10 | − | 1 5 |
| Right side of the equation = | x | × | 43617 25000 | − | 16 | − | 259 10 | − | 1 5 |
| = | 43617 25000 | x | − | 421 10 |
71803 250000 | = | 43617 25000 | x | − | 421 10 |
Transposition :
| - | 43617 25000 | x | = | - | 421 10 | − | 71803 250000 |
Combine the items on the right of the equation:
| - | 43617 25000 | x | = | - | 10596803 250000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
10596803 250000 | = | 43617 25000 | 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 :
43617 25000 | x | = | 10596803 250000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10596803 250000 | ÷ | 43617 25000 |
| = | 10596803 250000 | × | 25000 43617 |
| = | 1513829 10 | × | 1 6231 |
We obtained :
| x | = | 1513829 62310 |
Convert the result to decimal form :
| x | = | 24.295121 |
