Work: Find the solution of equation 10x = 0.41*0.173（10-10x+0.3）-0.71+0.056*3 .
Question type: Equation
Solution:Original question:
| 10 | x | = | 41 100 | × | 173 1000 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 71 100 | + | 7 125 | × | 3 |
| Right side of the equation = | 7093 100000 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 71 100 | + | 21 125 |
| = | 7093 100000 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 271 500 |
| 10 | x | = | 7093 100000 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 271 500 |
| Right side of the equation = | 7093 100000 | × | 10 | − | 7093 100000 | × | 10 | x | + | 7093 100000 | × | 3 10 | − | 271 500 |
| = | 7093 10000 | − | 7093 10000 | x | + | 21279 1000000 | − | 271 500 |
| = | 188579 1000000 | − | 7093 10000 | x |
| 10 | x | = | 188579 1000000 | − | 7093 10000 | x |
Transposition :
| 10 | x | + | 7093 10000 | x | = | 188579 1000000 |
Combine the items on the left of the equation:
107093 10000 | x | = | 188579 1000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 188579 1000000 | ÷ | 107093 10000 |
| = | 188579 1000000 | × | 10000 107093 |
| = | 188579 100 | × | 1 107093 |
We obtained :
| x | = | 188579 10709300 |
Convert the result to decimal form :
| x | = | 0.017609 |
