[ 1/1 Equation]
Work: Find the solution of equation 1284.4X-4000000-500X-(1284.4X*0.09-50X)*0.1 = 0 .
Question type: Equation
Solution:Original question:
6422 5 | X | − | 4000000 | − | 500 | X | − | ( | 6422 5 | X | × | 9 100 | − | 50 | X | ) | × | 1 10 | = | 0 |
| Left side of the equation = | 3922 5 | X | − | 4000000 | − | ( | 6422 5 | X | × | 9 100 | − | 50 | X | ) | × | 1 10 |
3922 5 | X | − | 4000000 | − | ( | 6422 5 | X | × | 9 100 | − | 50 | X | ) | × | 1 10 | = | 0 |
| Left side of the equation = | 3922 5 | X | − | 4000000 | − | 6422 5 | X | × | 9 100 | × | 1 10 | + | 50 | X | × | 1 10 |
| = | 3922 5 | X | − | 4000000 | − | 28899 2500 | X | + | 5 | X |
| = | 1944601 2500 | X | − | 4000000 |
1944601 2500 | X | − | 4000000 | = | 0 |
Transposition :
1944601 2500 | X | = | 0 | + | 4000000 |
Combine the items on the right of the equation:
1944601 2500 | X | = | 4000000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4000000 | ÷ | 1944601 2500 |
| = | 4000000 | × | 2500 1944601 |
We obtained :
| X | = | 10000000000 1944601 |
Convert the result to decimal form :
| X | = | 5142.443103 |
