Work: Find the solution of equation x+x/1.09*0.09*1.12+x/1.09*0.25 = 11800000 .
Question type: Equation
Solution:Original question:
| x | + | x | ÷ | 109 100 | × | 9 100 | × | 28 25 | + | x | ÷ | 109 100 | × | 1 4 | = | 11800000 |
| Left side of the equation = | x | + | x | × | 252 2725 | + | x | × | 25 109 |
| = | 3602 2725 | x |
3602 2725 | x | = | 11800000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11800000 | ÷ | 3602 2725 |
| = | 11800000 | × | 2725 3602 |
| = | 5900000 | × | 2725 1801 |
We obtained :
| x | = | 16077500000 1801 |
