Work: Find the solution of equation （39.402+x）×1.55 = 39.402+71.604-x .
Question type: Equation
Solution:Original question:
| ( | 19701 500 | + | x | ) | × | 31 20 | = | 19701 500 | + | 17901 250 | − | x |
| Left side of the equation = | 19701 500 | × | 31 20 | + | x | × | 31 20 |
| = | 610731 10000 | + | x | × | 31 20 |
610731 10000 | + | 31 20 | x | = | 19701 500 | + | 17901 250 | − | x |
| Right side of the equation = | 55503 500 | − | x |
610731 10000 | + | 31 20 | x | = | 55503 500 | − | x |
Transposition :
31 20 | x | + | x | = | 55503 500 | − | 610731 10000 |
Combine the items on the left of the equation:
51 20 | x | = | 55503 500 | − | 610731 10000 |
Combine the items on the right of the equation:
51 20 | x | = | 499329 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 499329 10000 | ÷ | 51 20 |
| = | 499329 10000 | × | 20 51 |
| = | 166443 500 | × | 1 17 |
We obtained :
| x | = | 166443 8500 |
Convert the result to decimal form :
| x | = | 19.581529 |
