Work: Find the solution of equation x/(3000000+0.1x) = 0.2024 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 3000000 | + | 1 10 | x | ) | = | 253 1250 |
| Multiply both sides of the equation by: | ( | 3000000 | + | 1 10 | x | ) |
| x | = | 253 1250 | ( | 3000000 | + | 1 10 | x | ) |
| x | = | 253 1250 | × | 3000000 | + | 253 1250 | × | 1 10 | x |
| x | = | 607200 | + | 253 12500 | x |
Transposition :
| x | − | 253 12500 | x | = | 607200 |
Combine the items on the left of the equation:
12247 12500 | x | = | 607200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 607200 | ÷ | 12247 12500 |
| = | 607200 | × | 12500 12247 |
We obtained :
| x | = | 7590000000 12247 |
Convert the result to decimal form :
| x | = | 619743.61068 |
