Work: Find the solution of equation 10x = 0.41（100-10x）*1.15-0*0.71 .
Question type: Equation
Solution:Original question:
| 10 | x | = | 41 100 | ( | 100 | − | 10 | x | ) | × | 23 20 | − | 0 | × | 71 100 |
| Right side of the equation = | 943 2000 | ( | 100 | − | 10 | x | ) | − | 0 |
| 10 | x | = | 943 2000 | ( | 100 | − | 10 | x | ) | − | 0 |
| Right side of the equation = | 943 2000 | × | 100 | − | 943 2000 | × | 10 | x | − | 0 |
| = | 943 20 | − | 943 200 | x | − | 0 |
| = | 943 20 | − | 943 200 | x |
| 10 | x | = | 943 20 | − | 943 200 | x |
Transposition :
| 10 | x | + | 943 200 | x | = | 943 20 |
Combine the items on the left of the equation:
2943 200 | x | = | 943 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 943 20 | ÷ | 2943 200 |
| = | 943 20 | × | 200 2943 |
| = | 943 | × | 10 2943 |
We obtained :
| x | = | 9430 2943 |
Convert the result to decimal form :
| x | = | 3.204213 |
