[ 1/1 Equation]
Work: Find the solution of equation 56x-40x-580-（56x-5）*0.13*0.12 = 0 .
Question type: Equation
Solution:Original question:
| 56 | x | − | 40 | x | − | 580 | − | ( | 56 | x | − | 5 | ) | × | 13 100 | × | 3 25 | = | 0 |
| Left side of the equation = | 56 | x | − | 40 | x | − | 580 | − | ( | 56 | x | − | 5 | ) | × | 39 2500 |
| = | 16 | x | − | 580 | − | ( | 56 | x | − | 5 | ) | × | 39 2500 |
| 16 | x | − | 580 | − | ( | 56 | x | − | 5 | ) | × | 39 2500 | = | 0 |
| Left side of the equation = | 16 | x | − | 580 | − | 56 | x | × | 39 2500 | + | 5 | × | 39 2500 |
| = | 16 | x | − | 580 | − | 546 625 | x | + | 39 500 |
| = | 9454 625 | x | − | 289961 500 |
9454 625 | x | − | 289961 500 | = | 0 |
Transposition :
9454 625 | x | = | 0 | + | 289961 500 |
Combine the items on the right of the equation:
9454 625 | x | = | 289961 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 289961 500 | ÷ | 9454 625 |
| = | 289961 500 | × | 625 9454 |
| = | 289961 4 | × | 5 9454 |
We obtained :
| x | = | 1449805 37816 |
Convert the result to decimal form :
| x | = | 38.338402 |
