Work: Find the solution of equation x/（385-x-18.06） = 0.3 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 385 | − | x | − | 903 50 | ) | = | 3 10 |
| Multiply both sides of the equation by: | ( | 385 | − | x | − | 903 50 | ) |
| x | = | 3 10 | ( | 385 | − | x | − | 903 50 | ) |
| x | = | 3 10 | × | 385 | − | 3 10 | x | − | 3 10 | × | 903 50 |
| x | = | 231 2 | − | 3 10 | x | − | 2709 500 |
| x | = | 55041 500 | − | 3 10 | x |
Transposition :
| x | + | 3 10 | x | = | 55041 500 |
Combine the items on the left of the equation:
13 10 | x | = | 55041 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 55041 500 | ÷ | 13 10 |
| = | 55041 500 | × | 10 13 |
| = | 55041 50 | × | 1 13 |
We obtained :
| x | = | 55041 650 |
Convert the result to decimal form :
| x | = | 84.678462 |
