Work: Find the solution of equation 12.9 = 11.5+0.04/(0.04+0.96x)*4.1 .
Question type: Equation
Solution:Original question:
129 10 | = | 23 2 | + | 1 25 | ÷ | ( | 1 25 | + | 24 25 | x | ) | × | 41 10 |
| Multiply both sides of the equation by: | ( | 1 25 | + | 24 25 | x | ) |
129 10 | ( | 1 25 | + | 24 25 | x | ) | = | 23 2 | ( | 1 25 | + | 24 25 | x | ) | + | 1 25 | × | 41 10 |
129 10 | × | 1 25 | + | 129 10 | × | 24 25 | x | = | 23 2 | ( | 1 25 | + | 24 25 | x | ) | + | 1 25 | × | 41 10 |
129 10 | × | 1 25 | + | 129 10 | × | 24 25 | x | = | 23 2 | × | 1 25 | + | 23 2 | × | 24 25 | x | + | 1 25 | × | 41 10 |
129 250 | + | 1548 125 | x | = | 23 50 | + | 276 25 | x | + | 41 250 |
129 250 | + | 1548 125 | x | = | 78 125 | + | 276 25 | x |
Transposition :
1548 125 | x | − | 276 25 | x | = | 78 125 | − | 129 250 |
Combine the items on the left of the equation:
168 125 | x | = | 78 125 | − | 129 250 |
Combine the items on the right of the equation:
168 125 | x | = | 27 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 27 250 | ÷ | 168 125 |
| = | 27 250 | × | 125 168 |
| = | 9 2 | × | 1 56 |
We obtained :
| x | = | 9 112 |
Convert the result to decimal form :
| x | = | 0.080357 |
