Work: Find the solution of equation 100/S(50S+4)+2 = 0 .
Question type: Equation
Solution:Original question:
| 100 | ÷ | S | × | ( | 50 | S | + | 4 | ) | + | 2 | = | 0 |
| Multiply both sides of the equation by: | S |
| 100 | ( | 50 | S | + | 4 | ) | + | 2 | S | = | 0 |
| 100 | × | 50 | S | + | 100 | × | 4 | + | 2 | S | = | 0 |
| 5000 | S | + | 400 | + | 2 | S | = | 0 |
| 5002 | S | + | 400 | = | 0 |
Transposition :
| 5002 | S | = | 0 | − | 400 |
Combine the items on the right of the equation:
| 5002 | S | = | - | 400 |
The coefficient of the unknown number is reduced to 1 :
| S | = | - | 400 | ÷ | 5002 |
| = | - | 400 | × | 1 5002 |
| = | - | 200 | × | 1 2501 |
We obtained :
| S | = | - | 200 2501 |
Convert the result to decimal form :
| S | = | - 0.079968 |
