Work: Find the solution of equation x/(x+1.8) = 0.631/3.3 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | x | + | 9 5 | ) | = | 631 1000 | ÷ | 33 10 |
| Multiply both sides of the equation by: | ( | x | + | 9 5 | ) |
| x | = | 631 1000 | ÷ | 33 10 | × | ( | x | + | 9 5 | ) |
| x | = | 631 1000 | ÷ | 33 10 | × | x | + | 631 1000 | ÷ | 33 10 | × | 9 5 |
| x | = | 631 3300 | x | + | 1893 5500 |
Transposition :
| x | − | 631 3300 | x | = | 1893 5500 |
Combine the items on the left of the equation:
2669 3300 | x | = | 1893 5500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1893 5500 | ÷ | 2669 3300 |
| = | 1893 5500 | × | 3300 2669 |
| = | 1893 5 | × | 3 2669 |
We obtained :
| x | = | 5679 13345 |
Convert the result to decimal form :
| x | = | 0.425553 |
