Work: Find the solution of equation 8081.36-x = x/21.75*13 .
Question type: Equation
Solution:Original question:
202034 25 | − | x | = | x | ÷ | 87 4 | × | 13 |
| Right side of the equation = | x | × | 52 87 |
202034 25 | − | x | = | 52 87 | x |
Transposition :
| - | x | − | 52 87 | x | = | - | 202034 25 |
Combine the items on the left of the equation:
| - | 139 87 | x | = | - | 202034 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
202034 25 | = | 139 87 | 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 :
139 87 | x | = | 202034 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 202034 25 | ÷ | 139 87 |
| = | 202034 25 | × | 87 139 |
We obtained :
| x | = | 17576958 3475 |
Convert the result to decimal form :
| x | = | 5058.11741 |
