Work: Find the solution of equation 50.46*（1+a）*1.13 = 67.99 .
Question type: Equation
Solution:Original question:
2523 50 | ( | 1 | + | a | ) | × | 113 100 | = | 6799 100 |
| Left side of the equation = | 285099 5000 | ( | 1 | + | a | ) |
285099 5000 | ( | 1 | + | a | ) | = | 6799 100 |
| Left side of the equation = | 285099 5000 | × | 1 | + | 285099 5000 | a |
| = | 285099 5000 | + | 285099 5000 | a |
285099 5000 | + | 285099 5000 | a | = | 6799 100 |
Transposition :
285099 5000 | a | = | 6799 100 | − | 285099 5000 |
Combine the items on the right of the equation:
285099 5000 | a | = | 54851 5000 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 54851 5000 | ÷ | 285099 5000 |
| = | 54851 5000 | × | 5000 285099 |
| = | 54851 | × | 1 285099 |
We obtained :
| a | = | 54851 285099 |
Convert the result to decimal form :
| a | = | 0.192393 |
