Work: Find the solution of equation 5+0.0189x+4.5 = 0 .
Question type: Equation
Solution:Original question:
| 5 | + | 189 10000 | x | + | 9 2 | = | 0 |
| Left side of the equation = | 19 2 | + | 189 10000 | x |
19 2 | + | 189 10000 | x | = | 0 |
Transposition :
189 10000 | x | = | 0 | − | 19 2 |
Combine the items on the right of the equation:
189 10000 | x | = | - | 19 2 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 19 2 | ÷ | 189 10000 |
| = | - | 19 2 | × | 10000 189 |
| = | - | 19 | × | 5000 189 |
We obtained :
| x | = | - | 95000 189 |
Convert the result to decimal form :
| x | = | - 502.645503 |
