Work: Find the solution of equation （x-27937373.55）*0.05*0.05 = 220000 .
Question type: Equation
Solution:Original question:
| ( | x | − | 558747471 20 | ) | × | 1 20 | × | 1 20 | = | 220000 |
| Left side of the equation = | ( | x | − | 558747471 20 | ) | × | 1 400 |
| ( | x | − | 558747471 20 | ) | × | 1 400 | = | 220000 |
| Left side of the equation = | x | × | 1 400 | − | 558747471 20 | × | 1 400 |
| = | x | × | 1 400 | − | 558747471 8000 |
1 400 | x | − | 558747471 8000 | = | 220000 |
Transposition :
1 400 | x | = | 220000 | + | 558747471 8000 |
Combine the items on the right of the equation:
1 400 | x | = | 2318747471 8000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2318747471 8000 | ÷ | 1 400 |
| = | 2318747471 8000 | × | 400 |
| = | 2318747471 20 | × | 1 |
We obtained :
| x | = | 2318747471 20 |
Convert the result to decimal form :
| x | = | 115937373.549999997 |
