Work: Find the solution of equation 2% = 42.21*x+（1-x）*（-29.62%） .
Question type: Equation
Solution:Original question:
2 100 | = | 4221 100 | x | + | ( | 1 | − | x | ) | ( | - | 1481 5000 | ) |
| Right side of the equation = | 4221 100 | x | + | 1 | ( | - | 1481 5000 | ) | − | x | ( | - | 1481 5000 | ) |
| = | 4221 100 | x | − | 1 | × | 1481 5000 | − | x | ( | - | 1481 5000 | ) |
| = | 4221 100 | x | − | 1481 5000 | − | x | ( | - | 1481 5000 | ) |
| = | 4221 100 | x | − | 1481 5000 | + | x | × | 1481 5000 |
| = | 212531 5000 | x | − | 1481 5000 |
2 100 | = | 212531 5000 | x | − | 1481 5000 |
Transposition :
| - | 212531 5000 | x | = | - | 1481 5000 | − | 2 100 |
Combine the items on the right of the equation:
| - | 212531 5000 | x | = | - | 1581 5000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1581 5000 | = | 212531 5000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
212531 5000 | x | = | 1581 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1581 5000 | ÷ | 212531 5000 |
| = | 1581 5000 | × | 5000 212531 |
| = | 1581 | × | 1 212531 |
We obtained :
| x | = | 1581 212531 |
Convert the result to decimal form :
| x | = | 0.007439 |
