Work: Find the solution of equation [10x+（330-25+183.36+10）-（10x*0.13-25）*0.1]*0.75/700 = 7% .
Question type: Equation
Solution:Original question:
| ( | 10 | x | + | ( | 330 | − | 25 | + | 4584 25 | + | 10 | ) | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 1 10 | ) | × | 3 4 | ÷ | 700 | = | 7 100 |
| Left side of the equation = | ( | 10 | x | + | ( | 330 | − | 25 | + | 4584 25 | + | 10 | ) | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 1 10 | ) | × | 3 2800 |
| ( | 10 | x | + | ( | 330 | − | 25 | + | 4584 25 | + | 10 | ) | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 1 10 | ) | × | 3 2800 | = | 7 100 |
| Left side of the equation = | 10 | x | × | 3 2800 | + | ( | 330 | − | 25 | + | 4584 25 | + | 10 | ) | × | 3 2800 | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 1 10 | × | 3 2800 |
| = | 3 280 | x | + | ( | 330 | − | 25 | + | 4584 25 | + | 10 | ) | × | 3 2800 | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 3 28000 |
| = | 3 280 | x | + | 330 | × | 3 2800 | − | 25 | × | 3 2800 | + | 4584 25 | × | 3 2800 | + | 10 | × | 3 2800 | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 3 28000 |
| = | 3 280 | x | + | 99 280 | − | 3 112 | + | 1719 8750 | + | 3 280 | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 3 28000 |
| = | 3 280 | x | + | 37377 70000 | − | ( | 10 | x | × | 13 100 | − | 25 | ) | × | 3 28000 |
| = | 3 280 | x | + | 37377 70000 | − | 10 | x | × | 13 100 | × | 3 28000 | + | 25 | × | 3 28000 |
| = | 3 280 | x | + | 37377 70000 | − | 39 280000 | x | + | 3 1120 |
| = | 423 40000 | x | + | 75129 140000 |
423 40000 | x | + | 75129 140000 | = | 7 100 |
Transposition :
423 40000 | x | = | 7 100 | − | 75129 140000 |
Combine the items on the right of the equation:
423 40000 | x | = | - | 65329 140000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 65329 140000 | ÷ | 423 40000 |
| = | - | 65329 140000 | × | 40000 423 |
| = | - | 65329 7 | × | 2 423 |
We obtained :
| x | = | - | 130658 2961 |
Convert the result to decimal form :
| x | = | - 44.126309 |
