Work: Find the solution of equation 2500+X*0.001*2*0.66*0.66 = X*0.003/2 .
Question type: Equation
Solution:Original question:
| 2500 | + | X | × | 1 1000 | × | 2 | × | 33 50 | × | 33 50 | = | X | × | 3 1000 | ÷ | 2 |
| Left side of the equation = | 2500 | + | X | × | 1089 1250000 |
| 2500 | + | 1089 1250000 | X | = | X | × | 3 1000 | ÷ | 2 |
| Right side of the equation = | X | × | 3 2000 |
| 2500 | + | 1089 1250000 | X | = | 3 2000 | X |
Transposition :
1089 1250000 | X | − | 3 2000 | X | = | - | 2500 |
Combine the items on the left of the equation:
| - | 393 625000 | X | = | - | 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 2500 | = | 393 625000 | 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 :
393 625000 | X | = | 2500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2500 | ÷ | 393 625000 |
| = | 2500 | × | 625000 393 |
We obtained :
| X | = | 1562500000 393 |
Convert the result to decimal form :
| X | = | 3975826.97201 |
