Work: Find the solution of equation 101.9 = 5/（1+x） .
Question type: Equation
Solution:Original question:
1019 10 | = | 5 | ÷ | ( | 1 | + | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
1019 10 | ( | 1 | + | x | ) | = | 5 |
1019 10 | × | 1 | + | 1019 10 | x | = | 5 |
1019 10 | + | 1019 10 | x | = | 5 |
Transposition :
1019 10 | x | = | 5 | − | 1019 10 |
Combine the items on the right of the equation:
1019 10 | x | = | - | 969 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 969 10 | ÷ | 1019 10 |
| = | - | 969 10 | × | 10 1019 |
| = | - | 969 | × | 1 1019 |
We obtained :
| x | = | - | 969 1019 |
Convert the result to decimal form :
| x | = | - 0.950932 |
