Work: Find the solution of equation x/0.09+(47778.05-x)/0.13 = 445268.43 .
Question type: Equation
Solution:Original question:
| x | ÷ | 9 100 | + | ( | 955561 20 | − | x | ) | ÷ | 13 100 | = | 44526843 100 |
| Left side of the equation = | 100 9 | x | + | 955561 20 | × | 100 13 | − | x | × | 100 13 |
| = | 100 9 | x | + | 4777805 13 | − | x | × | 100 13 |
| = | 400 117 | x | + | 4777805 13 |
400 117 | x | + | 4777805 13 | = | 44526843 100 |
Transposition :
400 117 | x | = | 44526843 100 | − | 4777805 13 |
Combine the items on the right of the equation:
400 117 | x | = | 101068459 1300 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 101068459 1300 | ÷ | 400 117 |
| = | 101068459 1300 | × | 117 400 |
We obtained :
| x | = | 11825009703 520000 |
