Work: Find the solution of equation 0.312 = (2.46x)/(1+1.46x) .
Question type: Equation
Solution:Original question:
39 125 | = | ( | 123 50 | x | ) | ÷ | ( | 1 | + | 73 50 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 73 50 | x | ) |
39 125 | ( | 1 | + | 73 50 | x | ) | = | ( | 123 50 | x | ) |
39 125 | × | 1 | + | 39 125 | × | 73 50 | x | = | ( | 123 50 | x | ) |
39 125 | × | 1 | + | 39 125 | × | 73 50 | x | = | 123 50 | x |
39 125 | + | 2847 6250 | x | = | 123 50 | x |
Transposition :
2847 6250 | x | − | 123 50 | x | = | - | 39 125 |
Combine the items on the left of the equation:
| - | 6264 3125 | x | = | - | 39 125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
39 125 | = | 6264 3125 | 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 :
6264 3125 | x | = | 39 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 39 125 | ÷ | 6264 3125 |
| = | 39 125 | × | 3125 6264 |
| = | 13 | × | 25 2088 |
We obtained :
| x | = | 325 2088 |
Convert the result to decimal form :
| x | = | 0.155651 |
