[ 1/1 Equation]
Work: Find the solution of equation 1.5/28000 = 1.41/(14100+x) .
Question type: Equation
Solution:Original question:
3 2 | ÷ | 28000 | = | 141 100 | ÷ | ( | 14100 | + | x | ) |
| Multiply both sides of the equation by: | ( | 14100 | + | x | ) |
3 2 | ÷ | 28000 | × | ( | 14100 | + | x | ) | = | 141 100 |
3 2 | ÷ | 28000 | × | 14100 | + | 3 2 | ÷ | 28000 | × | x | = | 141 100 |
423 560 | + | 3 56000 | x | = | 141 100 |
Transposition :
3 56000 | x | = | 141 100 | − | 423 560 |
Combine the items on the right of the equation:
3 56000 | x | = | 1833 2800 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1833 2800 | ÷ | 3 56000 |
| = | 1833 2800 | × | 56000 3 |
| = | 611 | × | 20 |
We obtained :
| x | = | 12220 |
