Work: Find the solution of equation （25.343+x）×0.85 = 50.687+66.83-x .
Question type: Equation
Solution:Original question:
| ( | 25343 1000 | + | x | ) | × | 17 20 | = | 50687 1000 | + | 6683 100 | − | x |
| Left side of the equation = | 25343 1000 | × | 17 20 | + | x | × | 17 20 |
| = | 430831 20000 | + | x | × | 17 20 |
430831 20000 | + | 17 20 | x | = | 50687 1000 | + | 6683 100 | − | x |
| Right side of the equation = | 117517 1000 | − | x |
430831 20000 | + | 17 20 | x | = | 117517 1000 | − | x |
Transposition :
17 20 | x | + | x | = | 117517 1000 | − | 430831 20000 |
Combine the items on the left of the equation:
37 20 | x | = | 117517 1000 | − | 430831 20000 |
Combine the items on the right of the equation:
37 20 | x | = | 1919509 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1919509 20000 | ÷ | 37 20 |
| = | 1919509 20000 | × | 20 37 |
| = | 1919509 1000 | × | 1 37 |
We obtained :
| x | = | 1919509 37000 |
Convert the result to decimal form :
| x | = | 51.878622 |
