Work: Find the solution of equation x-221.81-（x-221.81-5000）*3% = 5314.86 .
Question type: Equation
Solution:Original question:
| x | − | 22181 100 | − | ( | x | − | 22181 100 | − | 5000 | ) | × | 3 100 | = | 265743 50 |
| Left side of the equation = | x | − | 22181 100 | − | x | × | 3 100 | + | 22181 100 | × | 3 100 | + | 5000 | × | 3 100 |
| = | x | − | 22181 100 | − | x | × | 3 100 | + | 66543 10000 | + | 150 |
| = | 97 100 | x | − | 651557 10000 |
97 100 | x | − | 651557 10000 | = | 265743 50 |
Transposition :
97 100 | x | = | 265743 50 | + | 651557 10000 |
Combine the items on the right of the equation:
97 100 | x | = | 53800157 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 53800157 10000 | ÷ | 97 100 |
| = | 53800157 10000 | × | 100 97 |
| = | 53800157 100 | × | 1 97 |
We obtained :
| x | = | 53800157 9700 |
Convert the result to decimal form :
| x | = | 5546.407938 |
