Work: Find the solution of equation （800+X-12168.93）*(1-25%)+5213.15 = 5634.18 .
Question type: Equation
Solution:Original question:
| ( | 800 | + | X | − | 1216893 100 | ) | ( | 1 | − | 25 100 | ) | + | 104263 20 | = | 281709 50 |
| Left side of the equation = | 800 | ( | 1 | − | 25 100 | ) | + | X | ( | 1 | − | 25 100 | ) | − | 1216893 100 | ( | 1 | − | 25 100 | ) | + | 104263 20 |
| = | 800 | × | 1 | − | 800 | × | 25 100 | + | X | ( | 1 | − | 25 100 | ) | − | 1216893 100 | ( | 1 | − | 25 100 | ) | + | 104263 20 |
| = | 800 | − | 200 | + | X | ( | 1 | − | 25 100 | ) | − | 1216893 100 | ( | 1 | − | 25 100 | ) | + | 104263 20 |
| = | 116263 20 | + | X | ( | 1 | − | 25 100 | ) | − | 1216893 100 | ( | 1 | − | 25 100 | ) |
| = | 116263 20 | + | X | × | 1 | − | X | × | 25 100 | − | 1216893 100 | ( | 1 | − | 25 100 | ) |
| = | 116263 20 | + | 3 4 | X | − | 1216893 100 | ( | 1 | − | 25 100 | ) |
| = | 116263 20 | + | 3 4 | X | − | 1216893 100 | × | 1 | + | 1216893 100 | × | 25 100 |
| = | 116263 20 | + | 3 4 | X | − | 1216893 100 | + | 1216893 400 |
| = | - | 1325419 400 | + | 3 4 | X |
| - | 1325419 400 | + | 3 4 | X | = | 281709 50 |
Transposition :
3 4 | X | = | 281709 50 | + | 1325419 400 |
Combine the items on the right of the equation:
3 4 | X | = | 3579091 400 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 3579091 400 | ÷ | 3 4 |
| = | 3579091 400 | × | 4 3 |
| = | 3579091 100 | × | 1 3 |
We obtained :
| X | = | 3579091 300 |
Convert the result to decimal form :
| X | = | 11930.303333 |
