Work: Find the solution of equation 10x = 0.41*0.8（10-10x+0.3）-0.71+0.056*3 .
Question type: Equation
Solution:Original question:
| 10 | x | = | 41 100 | × | 4 5 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 71 100 | + | 7 125 | × | 3 |
| Right side of the equation = | 41 125 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 71 100 | + | 21 125 |
| = | 41 125 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 271 500 |
| 10 | x | = | 41 125 | ( | 10 | − | 10 | x | + | 3 10 | ) | − | 271 500 |
| Right side of the equation = | 41 125 | × | 10 | − | 41 125 | × | 10 | x | + | 41 125 | × | 3 10 | − | 271 500 |
| = | 82 25 | − | 82 25 | x | + | 123 1250 | − | 271 500 |
| = | 7091 2500 | − | 82 25 | x |
| 10 | x | = | 7091 2500 | − | 82 25 | x |
Transposition :
| 10 | x | + | 82 25 | x | = | 7091 2500 |
Combine the items on the left of the equation:
332 25 | x | = | 7091 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7091 2500 | ÷ | 332 25 |
| = | 7091 2500 | × | 25 332 |
| = | 7091 100 | × | 1 332 |
We obtained :
| x | = | 7091 33200 |
Convert the result to decimal form :
| x | = | 0.213584 |
