Work: Find the solution of equation 0.907*（-26460）-7.81*2.8+（8400+x）*2.3469 = 0 .
Question type: Equation
Solution:Original question:
907 1000 | ( | - | 26460 | ) | − | 781 100 | × | 14 5 | + | ( | 8400 | + | x | ) | × | 23469 10000 | = | 0 |
| Left side of the equation = | 907 1000 | ( | - | 26460 | ) | − | 5467 250 | + | ( | 8400 | + | x | ) | × | 23469 10000 |
907 1000 | ( | - | 26460 | ) | − | 5467 250 | + | ( | 8400 | + | x | ) | × | 23469 10000 | = | 0 |
| Left side of the equation = | - | 907 1000 | × | 26460 | − | 5467 250 | + | ( | 8400 | + | x | ) | × | 23469 10000 |
| = | - | 1199961 50 | − | 5467 250 | + | ( | 8400 | + | x | ) | × | 23469 10000 |
| = | - | 3002636 125 | + | ( | 8400 | + | x | ) | × | 23469 10000 |
| = | - | 3002636 125 | + | 8400 | × | 23469 10000 | + | x | × | 23469 10000 |
| = | - | 3002636 125 | + | 492849 25 | + | x | × | 23469 10000 |
| = | - | 538391 125 | + | 23469 10000 | x |
| - | 538391 125 | + | 23469 10000 | x | = | 0 |
Transposition :
23469 10000 | x | = | 0 | + | 538391 125 |
Combine the items on the right of the equation:
23469 10000 | x | = | 538391 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 538391 125 | ÷ | 23469 10000 |
| = | 538391 125 | × | 10000 23469 |
| = | 538391 | × | 80 23469 |
We obtained :
| x | = | 43071280 23469 |
Convert the result to decimal form :
| x | = | 1835.241382 |
