Work: Find the solution of equation （x-x*5.03%*0.03%）-647000*0.03% = 647000 .
Question type: Equation
Solution:Original question:
| ( | x | − | x | × | 503 10000 | × | 3 10000 | ) | − | 647000 | × | 3 10000 | = | 647000 |
| Left side of the equation = | ( | x | − | x | × | 503 10000 | × | 3 10000 | ) | − | 1941 10 |
| ( | x | − | x | × | 503 10000 | × | 3 10000 | ) | − | 1941 10 | = | 647000 |
| Left side of the equation = | x | − | x | × | 503 10000 | × | 3 10000 | − | 1941 10 |
| = | x | − | x | × | 1509 100000000 | − | 1941 10 |
| = | 99998491 100000000 | x | − | 1941 10 |
99998491 100000000 | x | − | 1941 10 | = | 647000 |
Transposition :
99998491 100000000 | x | = | 647000 | + | 1941 10 |
Combine the items on the right of the equation:
99998491 100000000 | x | = | 6471941 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6471941 10 | ÷ | 99998491 100000000 |
| = | 6471941 10 | × | 100000000 99998491 |
| = | 6471941 | × | 10000000 99998491 |
We obtained :
| x | = | 64719410000000 99998491 |
