Work: Find the solution of equation X-[(70274.03+X-30000-3715.5)*0.1-2520-1697.78]-619.25 = 8000 .
Question type: Equation
Solution:Original question:
| X | − | ( | ( | 7027403 100 | + | X | − | 30000 | − | 7431 2 | ) | × | 1 10 | − | 2520 | − | 84889 50 | ) | − | 2477 4 | = | 8000 |
| Left side of the equation = | X | − | ( | 7027403 100 | + | X | − | 30000 | − | 7431 2 | ) | × | 1 10 | + | 2520 | + | 84889 50 | − | 2477 4 |
| = | X | − | ( | 7027403 100 | + | X | − | 30000 | − | 7431 2 | ) | × | 1 10 | + | 359853 100 |
| = | X | − | 7027403 100 | × | 1 10 | − | X | × | 1 10 | + | 30000 | × | 1 10 | + | 7431 2 | × | 1 10 | + | 359853 100 |
| = | X | − | 7027403 1000 | − | X | × | 1 10 | + | 3000 | + | 7431 20 | + | 359853 100 |
| = | 9 10 | X | − | 57323 1000 |
9 10 | X | − | 57323 1000 | = | 8000 |
Transposition :
9 10 | X | = | 8000 | + | 57323 1000 |
Combine the items on the right of the equation:
9 10 | X | = | 8057323 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 8057323 1000 | ÷ | 9 10 |
| = | 8057323 1000 | × | 10 9 |
| = | 8057323 100 | × | 1 9 |
We obtained :
| X | = | 8057323 900 |
Convert the result to decimal form :
| X | = | 8952.581111 |
