Work: Find the solution of equation 7.0 = 7.21+（x/200-x） .
Question type: Equation
Solution:Original question:
| 7 | = | 721 100 | + | ( | x | ÷ | 200 | − | x | ) |
| Right side of the equation = | 721 100 | + | x | ÷ | 200 | − | x |
| = | 721 100 | − | 199 200 | x |
| 7 | = | 721 100 | − | 199 200 | x |
Transposition :
199 200 | x | = | 721 100 | − | 7 |
Combine the items on the right of the equation:
199 200 | x | = | 21 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 21 100 | ÷ | 199 200 |
| = | 21 100 | × | 200 199 |
| = | 21 | × | 2 199 |
We obtained :
| x | = | 42 199 |
Convert the result to decimal form :
| x | = | 0.211055 |
