Work: Find the solution of equation 0.8(1+x)/(0.12-x) = 29.07 .
Question type: Equation
Solution:Original question:
4 5 | ( | 1 | + | x | ) | ÷ | ( | 3 25 | − | x | ) | = | 2907 100 |
| Multiply both sides of the equation by: | ( | 3 25 | − | x | ) |
4 5 | ( | 1 | + | x | ) | = | 2907 100 | ( | 3 25 | − | x | ) |
4 5 | × | 1 | + | 4 5 | x | = | 2907 100 | ( | 3 25 | − | x | ) |
4 5 | × | 1 | + | 4 5 | x | = | 2907 100 | × | 3 25 | − | 2907 100 | x |
4 5 | + | 4 5 | x | = | 8721 2500 | − | 2907 100 | x |
Transposition :
4 5 | x | + | 2907 100 | x | = | 8721 2500 | − | 4 5 |
Combine the items on the left of the equation:
2987 100 | x | = | 8721 2500 | − | 4 5 |
Combine the items on the right of the equation:
2987 100 | x | = | 6721 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6721 2500 | ÷ | 2987 100 |
| = | 6721 2500 | × | 100 2987 |
| = | 6721 25 | × | 1 2987 |
We obtained :
| x | = | 6721 74675 |
Convert the result to decimal form :
| x | = | 0.090003 |
