Work: Find the solution of equation 0.457 = (2.46x)/(1+1.46x) .
Question type: Equation
Solution:Original question:
457 1000 | = | ( | 123 50 | x | ) | ÷ | ( | 1 | + | 73 50 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 73 50 | x | ) |
457 1000 | ( | 1 | + | 73 50 | x | ) | = | ( | 123 50 | x | ) |
457 1000 | × | 1 | + | 457 1000 | × | 73 50 | x | = | ( | 123 50 | x | ) |
457 1000 | × | 1 | + | 457 1000 | × | 73 50 | x | = | 123 50 | x |
457 1000 | + | 33361 50000 | x | = | 123 50 | x |
Transposition :
33361 50000 | x | − | 123 50 | x | = | - | 457 1000 |
Combine the items on the left of the equation:
| - | 89639 50000 | x | = | - | 457 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
457 1000 | = | 89639 50000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
89639 50000 | x | = | 457 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 457 1000 | ÷ | 89639 50000 |
| = | 457 1000 | × | 50000 89639 |
| = | 457 | × | 50 89639 |
We obtained :
| x | = | 22850 89639 |
Convert the result to decimal form :
| x | = | 0.254911 |
