Work: Find the solution of equation (39/(10+x)+1)*0.765 = 0 .
Question type: Equation
Solution:Original question:
| ( | 39 | ÷ | ( | 10 | + | x | ) | + | 1 | ) | × | 153 200 | = | 0 |
| 39 | ÷ | ( | 10 | + | x | ) | × | 153 200 | + | 1 | × | 153 200 | = | 0 |
5967 200 | ÷ | ( | 10 | + | x | ) | + | 153 200 | = | 0 |
| Multiply both sides of the equation by: | ( | 10 | + | x | ) |
5967 200 | + | 153 200 | ( | 10 | + | x | ) | = | 0 |
5967 200 | + | 153 200 | × | 10 | + | 153 200 | x | = | 0 |
5967 200 | + | 153 20 | + | 153 200 | x | = | 0 |
7497 200 | + | 153 200 | x | = | 0 |
Transposition :
153 200 | x | = | 0 | − | 7497 200 |
Combine the items on the right of the equation:
153 200 | x | = | - | 7497 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 7497 200 | ÷ | 153 200 |
| = | - | 7497 200 | × | 200 153 |
| = | - | 49 | × | 1 |
We obtained :
| x | = | - | 49 |
