Work: Find the solution of equation x/（5534451-0.9x） = 0.1805 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 5534451 | − | 9 10 | x | ) | = | 361 2000 |
| Multiply both sides of the equation by: | ( | 5534451 | − | 9 10 | x | ) |
| x | = | 361 2000 | ( | 5534451 | − | 9 10 | x | ) |
| x | = | 361 2000 | × | 5534451 | − | 361 2000 | × | 9 10 | x |
| x | = | 1997936811 2000 | − | 3249 20000 | x |
Transposition :
| x | + | 3249 20000 | x | = | 1997936811 2000 |
Combine the items on the left of the equation:
23249 20000 | x | = | 1997936811 2000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1997936811 2000 | ÷ | 23249 20000 |
| = | 1997936811 2000 | × | 20000 23249 |
| = | 1997936811 | × | 10 23249 |
We obtained :
| x | = | 19979368110 23249 |
