Work: Find the solution of equation 15.68/(0.02-10x) = 78.4/(0.08-5x) .
Question type: Equation
Solution:Original question:
392 25 | ÷ | ( | 1 50 | − | 10 | x | ) | = | 392 5 | ÷ | ( | 2 25 | − | 5 | x | ) |
| Multiply both sides of the equation by: | ( | 1 50 | − | 10 | x | ) | , | ( | 2 25 | − | 5 | x | ) |
392 25 | ( | 2 25 | − | 5 | x | ) | = | 392 5 | ( | 1 50 | − | 10 | x | ) |
392 25 | × | 2 25 | − | 392 25 | × | 5 | x | = | 392 5 | ( | 1 50 | − | 10 | x | ) |
392 25 | × | 2 25 | − | 392 25 | × | 5 | x | = | 392 5 | × | 1 50 | − | 392 5 | × | 10 | x |
784 625 | − | 392 5 | x | = | 196 125 | − | 784 | x |
Transposition :
| - | 392 5 | x | + | 784 | x | = | 196 125 | − | 784 625 |
Combine the items on the left of the equation:
3528 5 | x | = | 196 125 | − | 784 625 |
Combine the items on the right of the equation:
3528 5 | x | = | 196 625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 196 625 | ÷ | 3528 5 |
| = | 196 625 | × | 5 3528 |
| = | 1 125 | × | 1 18 |
We obtained :
| x | = | 1 2250 |
Convert the result to decimal form :
| x | = | 0.000444 |
