Work: Find the solution of equation （10841.25+20+X）*3.1% = （360/210）*X .
Question type: Equation
Solution:Original question:
| ( | 43365 4 | + | 20 | + | X | ) | × | 31 1000 | = | ( | 360 | ÷ | 210 | ) | X |
| Left side of the equation = | 43365 4 | × | 31 1000 | + | 20 | × | 31 1000 | + | X | × | 31 1000 |
| = | 268863 800 | + | 31 50 | + | X | × | 31 1000 |
| = | 269359 800 | + | 31 1000 | X |
269359 800 | + | 31 1000 | X | = | ( | 360 | ÷ | 210 | ) | X |
| Right side of the equation = | 360 | ÷ | 210 | × | X |
| = | 12 7 | X |
269359 800 | + | 31 1000 | X | = | 12 7 | X |
Transposition :
31 1000 | X | − | 12 7 | X | = | - | 269359 800 |
Combine the items on the left of the equation:
| - | 11783 7000 | X | = | - | 269359 800 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
269359 800 | = | 11783 7000 | 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 :
11783 7000 | X | = | 269359 800 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 269359 800 | ÷ | 11783 7000 |
| = | 269359 800 | × | 7000 11783 |
| = | 269359 4 | × | 35 11783 |
We obtained :
| X | = | 9427565 47132 |
Convert the result to decimal form :
| X | = | 200.024718 |
