[ 1/1 Equation]
Work: Find the solution of equation 0.125*3*x/（0.125*x+3）-17.88 = 0 .
Question type: Equation
Solution:Original question:
1 8 | × | 3 | x | ÷ | ( | 1 8 | x | + | 3 | ) | − | 447 25 | = | 0 |
| Multiply both sides of the equation by: | ( | 1 8 | x | + | 3 | ) |
1 8 | × | 3 | x | − | 447 25 | ( | 1 8 | x | + | 3 | ) | = | 0 |
1 8 | × | 3 | x | − | 447 25 | × | 1 8 | x | − | 447 25 | × | 3 | = | 0 |
3 8 | x | − | 447 200 | x | − | 1341 25 | = | 0 |
| - | 93 50 | x | − | 1341 25 | = | 0 |
Transposition :
| - | 93 50 | x | = | 0 | + | 1341 25 |
Combine the items on the right of the equation:
| - | 93 50 | x | = | 1341 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 1341 25 | = | 93 50 | 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 :
93 50 | x | = | - | 1341 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1341 25 | ÷ | 93 50 |
| = | - | 1341 25 | × | 50 93 |
| = | - | 447 | × | 2 31 |
We obtained :
| x | = | - | 894 31 |
Convert the result to decimal form :
| x | = | - 28.83871 |
