Work: Find the solution of equation X-(71026.95-22230.36+X-25000-3096.25)*0.1-2520-789.59 = 19950 .
Question type: Equation
Solution:Original question:
| X | − | ( | 1420539 20 | − | 555759 25 | + | X | − | 25000 | − | 12385 4 | ) | × | 1 10 | − | 2520 | − | 78959 100 | = | 19950 |
| Left side of the equation = | X | − | ( | 1420539 20 | − | 555759 25 | + | X | − | 25000 | − | 12385 4 | ) | × | 1 10 | − | 330959 100 |
| X | − | ( | 1420539 20 | − | 555759 25 | + | X | − | 25000 | − | 12385 4 | ) | × | 1 10 | − | 330959 100 | = | 19950 |
| Left side of the equation = | X | − | 1420539 20 | × | 1 10 | + | 555759 25 | × | 1 10 | − | X | × | 1 10 | + | 25000 | × | 1 10 | + | 12385 4 | × | 1 10 | − | 330959 100 |
| = | X | − | 1420539 200 | + | 555759 250 | − | X | × | 1 10 | + | 2500 | + | 2477 8 | − | 330959 100 |
| = | 9 10 | X | − | 672453 125 |
9 10 | X | − | 672453 125 | = | 19950 |
Transposition :
9 10 | X | = | 19950 | + | 672453 125 |
Combine the items on the right of the equation:
9 10 | X | = | 3166203 125 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 3166203 125 | ÷ | 9 10 |
| = | 3166203 125 | × | 10 9 |
| = | 1055401 25 | × | 2 3 |
We obtained :
| X | = | 2110802 75 |
Convert the result to decimal form :
| X | = | 28144.026667 |
