Work: Find the solution of equation 72.0057+x*0.012%+x*0.1% = x .
Question type: Equation
Solution:Original question:
720057 10000 | + | x | × | 3 25000 | + | x | × | 1 1000 | = | x |
| Left side of the equation = | 720057 10000 | + | 7 6250 | x |
720057 10000 | + | 7 6250 | x | = | x |
Transposition :
7 6250 | x | − | x | = | - | 720057 10000 |
Combine the items on the left of the equation:
| - | 6243 6250 | x | = | - | 720057 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
720057 10000 | = | 6243 6250 | 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 :
6243 6250 | x | = | 720057 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 720057 10000 | ÷ | 6243 6250 |
| = | 720057 10000 | × | 6250 6243 |
| = | 240019 8 | × | 5 2081 |
We obtained :
| x | = | 1200095 16648 |
Convert the result to decimal form :
| x | = | 72.086437 |
