Work: Find the solution of equation 1.13x/0.13+1.03(114465.87-x)/0.03 = 1200642.48 .
Question type: Equation
Solution:Original question:
113 100 | x | ÷ | 13 100 | + | 103 100 | ( | 11446587 100 | − | x | ) | ÷ | 3 100 | = | 30016062 25 |
| Left side of the equation = | 113 13 | x | + | 103 3 | ( | 11446587 100 | − | x | ) |
113 13 | x | + | 103 3 | ( | 11446587 100 | − | x | ) | = | 30016062 25 |
| Left side of the equation = | 113 13 | x | + | 103 3 | × | 11446587 100 | − | 103 3 | x |
| = | 113 13 | x | + | 392999487 100 | − | 103 3 | x |
| = | - | 1000 39 | x | + | 392999487 100 |
| - | 1000 39 | x | + | 392999487 100 | = | 30016062 25 |
Transposition :
| - | 1000 39 | x | = | 30016062 25 | − | 392999487 100 |
Combine the items on the right of the equation:
| - | 1000 39 | x | = | - | 272935239 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
272935239 100 | = | 1000 39 | 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 :
1000 39 | x | = | 272935239 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 272935239 100 | ÷ | 1000 39 |
| = | 272935239 100 | × | 39 1000 |
We obtained :
| x | = | 10644474321 100000 |
