[ 1/1 Equation]
Work: Find the solution of equation （60a-2191.36-（60a*13%-170）*12%）*75% = 131.24 .
Question type: Equation
Solution:Original question:
| ( | 60 | a | − | 54784 25 | − | ( | 60 | a | × | 13 100 | − | 170 | ) | × | 12 100 | ) | × | 75 100 | = | 3281 25 |
| Left side of the equation = | 60 | a | × | 75 100 | − | 54784 25 | × | 75 100 | − | ( | 60 | a | × | 13 100 | − | 170 | ) | × | 12 100 | × | 75 100 |
| = | 45 | a | − | 41088 25 | − | ( | 60 | a | × | 13 100 | − | 170 | ) | × | 9 100 |
| = | 45 | a | − | 41088 25 | − | 60 | a | × | 13 100 | × | 9 100 | + | 170 | × | 9 100 |
| = | 45 | a | − | 41088 25 | − | 351 500 | a | + | 153 10 |
| = | 22149 500 | a | − | 81411 50 |
22149 500 | a | − | 81411 50 | = | 3281 25 |
Transposition :
22149 500 | a | = | 3281 25 | + | 81411 50 |
Combine the items on the right of the equation:
22149 500 | a | = | 87973 50 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 87973 50 | ÷ | 22149 500 |
| = | 87973 50 | × | 500 22149 |
| = | 87973 | × | 10 22149 |
We obtained :
| a | = | 879730 22149 |
Convert the result to decimal form :
| a | = | 39.718723 |
