Work: Find the solution of equation （5520715.59-x）*0.4/100 = x .
Question type: Equation
Solution:Original question:
| ( | 552071559 100 | − | x | ) | × | 2 5 | ÷ | 100 | = | x |
| Left side of the equation = | ( | 552071559 100 | − | x | ) | × | 1 250 |
| ( | 552071559 100 | − | x | ) | × | 1 250 | = | x |
| Left side of the equation = | 552071559 100 | × | 1 250 | − | x | × | 1 250 |
| = | 552071559 25000 | − | x | × | 1 250 |
552071559 25000 | − | 1 250 | x | = | x |
Transposition :
| - | 1 250 | x | − | x | = | - | 552071559 25000 |
Combine the items on the left of the equation:
| - | 251 250 | x | = | - | 552071559 25000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
552071559 25000 | = | 251 250 | 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 :
251 250 | x | = | 552071559 25000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 552071559 25000 | ÷ | 251 250 |
| = | 552071559 25000 | × | 250 251 |
| = | 552071559 100 | × | 1 251 |
We obtained :
| x | = | 552071559 25100 |
Convert the result to decimal form :
| x | = | 21994.882829 |
