Work: Find the solution of equation （9580+40+X）*（4.69125%+1.8%-1.25%） = 4X .
Question type: Equation
Solution:Original question:
| ( | 9580 | + | 40 | + | X | ) | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | = | 4 | X |
| Left side of the equation = | 9580 | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | + | 40 | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 9580 | × | 3753 80000 | + | 9580 | × | 9 500 | − | 9580 | × | 5 400 | + | 40 | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 1797687 4000 | + | 4311 25 | − | 479 4 | + | 40 | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 2008447 4000 | + | 40 | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 2008447 4000 | + | 40 | × | 3753 80000 | + | 40 | × | 9 500 | − | 40 | × | 5 400 | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 2008447 4000 | + | 3753 2000 | + | 18 25 | − | 1 2 | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 2016833 4000 | + | X | ( | 3753 80000 | + | 9 500 | − | 5 400 | ) |
| = | 2016833 4000 | + | X | × | 3753 80000 | + | X | × | 9 500 | − | X | × | 5 400 |
| = | 2016833 4000 | + | 4193 80000 | X |
2016833 4000 | + | 4193 80000 | X | = | 4 | X |
Transposition :
4193 80000 | X | − | 4 | X | = | - | 2016833 4000 |
Combine the items on the left of the equation:
| - | 315807 80000 | X | = | - | 2016833 4000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2016833 4000 | = | 315807 80000 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
315807 80000 | X | = | 2016833 4000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2016833 4000 | ÷ | 315807 80000 |
| = | 2016833 4000 | × | 80000 315807 |
| = | 2016833 | × | 20 315807 |
We obtained :
| X | = | 40336660 315807 |
Convert the result to decimal form :
| X | = | 127.725668 |
