Work: Find the solution of equation 0.36 = 1/2（118.93÷72.72＋x÷118.93）－1 .
Question type: Equation
Solution:Original question:
9 25 | = | 1 | ÷ | 2 | × | ( | 11893 100 | ÷ | 1818 25 | + | x | ÷ | 11893 100 | ) | − | 1 |
| Right side of the equation = | 1 2 | ( | 11893 100 | ÷ | 1818 25 | + | x | ÷ | 11893 100 | ) | − | 1 |
9 25 | = | 1 2 | ( | 11893 100 | ÷ | 1818 25 | + | x | ÷ | 11893 100 | ) | − | 1 |
| Right side of the equation = | 1 2 | × | 11893 100 | ÷ | 1818 25 | + | 1 2 | x | ÷ | 11893 100 | − | 1 |
| = | 11893 14544 | + | 50 11893 | x | − | 1 |
| = | - | 2651 14544 | + | 50 11893 | x |
9 25 | = | - | 2651 14544 | + | 50 11893 | x |
Transposition :
| - | 50 11893 | x | = | - | 2651 14544 | − | 9 25 |
Combine the items on the right of the equation:
| - | 50 11893 | x | = | - | 197171 363600 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
197171 363600 | = | 50 11893 | 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 :
50 11893 | x | = | 197171 363600 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 197171 363600 | ÷ | 50 11893 |
| = | 197171 363600 | × | 11893 50 |
We obtained :
| x | = | 2344954703 18180000 |
Convert the result to decimal form :
| x | = | 128.985407 |
