Work: Find the solution of equation 0.045455（16-x）+0.6x = 9 .
Question type: Equation
Solution:Original question:
9091 200000 | ( | 16 | − | x | ) | + | 3 5 | x | = | 9 |
| Left side of the equation = | 9091 200000 | × | 16 | − | 9091 200000 | x | + | 3 5 | x |
| = | 9091 12500 | − | 9091 200000 | x | + | 3 5 | x |
| = | 9091 12500 | + | 110909 200000 | x |
9091 12500 | + | 110909 200000 | x | = | 9 |
Transposition :
110909 200000 | x | = | 9 | − | 9091 12500 |
Combine the items on the right of the equation:
110909 200000 | x | = | 103409 12500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 103409 12500 | ÷ | 110909 200000 |
| = | 103409 12500 | × | 200000 110909 |
| = | 103409 | × | 16 110909 |
We obtained :
| x | = | 1654544 110909 |
Convert the result to decimal form :
| x | = | 14.918032 |
