Work: Find the solution of equation 100*（x-7.3%）*1.88 = 12.55 .
Question type: Equation
Solution:Original question:
| 100 | ( | x | − | 73 1000 | ) | × | 47 25 | = | 251 20 |
| Left side of the equation = | 188 | ( | x | − | 73 1000 | ) |
| 188 | ( | x | − | 73 1000 | ) | = | 251 20 |
| Left side of the equation = | 188 | x | − | 188 | × | 73 1000 |
| = | 188 | x | − | 3431 250 |
| 188 | x | − | 3431 250 | = | 251 20 |
Transposition :
| 188 | x | = | 251 20 | + | 3431 250 |
Combine the items on the right of the equation:
| 188 | x | = | 13137 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 13137 500 | ÷ | 188 |
| = | 13137 500 | × | 1 188 |
We obtained :
| x | = | 13137 94000 |
Convert the result to decimal form :
| x | = | 0.139755 |
