[ 1/1 Equation]
Work: Find the solution of equation x+455-(x-3655-6500)*0.03-3655 = 15393.9 .
Question type: Equation
Solution:Original question:
| x | + | 455 | − | ( | x | − | 3655 | − | 6500 | ) | × | 3 100 | − | 3655 | = | 153939 10 |
| Left side of the equation = | x | − | 3200 | − | ( | x | − | 3655 | − | 6500 | ) | × | 3 100 |
| x | − | 3200 | − | ( | x | − | 3655 | − | 6500 | ) | × | 3 100 | = | 153939 10 |
| Left side of the equation = | x | − | 3200 | − | x | × | 3 100 | + | 3655 | × | 3 100 | + | 6500 | × | 3 100 |
| = | x | − | 3200 | − | x | × | 3 100 | + | 2193 20 | + | 195 |
| = | 97 100 | x | − | 57907 20 |
97 100 | x | − | 57907 20 | = | 153939 10 |
Transposition :
97 100 | x | = | 153939 10 | + | 57907 20 |
Combine the items on the right of the equation:
97 100 | x | = | 73157 4 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 73157 4 | ÷ | 97 100 |
| = | 73157 4 | × | 100 97 |
| = | 73157 | × | 25 97 |
We obtained :
| x | = | 1828925 97 |
Convert the result to decimal form :
| x | = | 18854.896907 |
