[ 1/3 Equation]
Work: Find the solution of equation 15684468 = 15883821.05X+36944.2 .
Question type: Equation
Solution:Original question:
| 15684468 | = | 317676421 20 | X | + | 184721 5 |
Transposition :
| - | 317676421 20 | X | = | 184721 5 | − | 15684468 |
Combine the items on the right of the equation:
| - | 317676421 20 | X | = | - | 78237619 5 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
78237619 5 | = | 317676421 20 | 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 :
317676421 20 | X | = | 78237619 5 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 78237619 5 | ÷ | 317676421 20 |
| = | 78237619 5 | × | 20 317676421 |
| = | 78237619 | × | 4 317676421 |
We obtained :
| X | = | 312950476 317676421 |
Convert the result to decimal form :
| X | = | 0.985123 |
