Work: Find the solution of equation x/0.09+(174928.17-x)/0.13 = 1618582.78 .
Question type: Equation
Solution:Original question:
| x | ÷ | 9 100 | + | ( | 17492817 100 | − | x | ) | ÷ | 13 100 | = | 80929139 50 |
| Left side of the equation = | 100 9 | x | + | 17492817 100 | × | 100 13 | − | x | × | 100 13 |
| = | 100 9 | x | + | 17492817 13 | − | x | × | 100 13 |
| = | 400 117 | x | + | 17492817 13 |
400 117 | x | + | 17492817 13 | = | 80929139 50 |
Transposition :
400 117 | x | = | 80929139 50 | − | 17492817 13 |
Combine the items on the right of the equation:
400 117 | x | = | 177437957 650 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 177437957 650 | ÷ | 400 117 |
| = | 177437957 650 | × | 117 400 |
We obtained :
| x | = | 20760240969 260000 |
