[ 1/1 Equation]
Work: Find the solution of equation 11800000+x/1.09*0.09*1.12+x/1.09*0.25+x/1.09*0.03/100 = x .
Question type: Equation
Solution:Original question:
| 11800000 | + | x | ÷ | 109 100 | × | 9 100 | × | 28 25 | + | x | ÷ | 109 100 | × | 1 4 | + | x | ÷ | 109 100 | × | 3 100 | ÷ | 100 | = | x |
| Left side of the equation = | 11800000 | + | x | × | 252 2725 | + | x | × | 25 109 | + | x | × | 3 10900 |
| = | 11800000 | + | 3511 10900 | x |
| 11800000 | + | 3511 10900 | x | = | x |
Transposition :
3511 10900 | x | − | x | = | - | 11800000 |
Combine the items on the left of the equation:
| - | 7389 10900 | x | = | - | 11800000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 11800000 | = | 7389 10900 | 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 :
7389 10900 | x | = | 11800000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11800000 | ÷ | 7389 10900 |
| = | 11800000 | × | 10900 7389 |
We obtained :
| x | = | 128620000000 7389 |
