Work: Find the solution of equation (7148497.50+X)*0.2/1.05*0.05 = 0 .
Question type: Equation
Solution:Original question:
| ( | 14296995 2 | + | X | ) | × | 1 5 | ÷ | 21 20 | × | 1 20 | = | 0 |
| Left side of the equation = | ( | 14296995 2 | + | X | ) | × | 1 105 |
| ( | 14296995 2 | + | X | ) | × | 1 105 | = | 0 |
| Left side of the equation = | 14296995 2 | × | 1 105 | + | X | × | 1 105 |
| = | 953133 14 | + | X | × | 1 105 |
953133 14 | + | 1 105 | X | = | 0 |
Transposition :
1 105 | X | = | 0 | − | 953133 14 |
Combine the items on the right of the equation:
1 105 | X | = | - | 953133 14 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 953133 14 | ÷ | 1 105 |
| = | - | 953133 14 | × | 105 |
| = | - | 953133 2 | × | 15 |
We obtained :
| X | = | - | 14296995 2 |
Convert the result to decimal form :
| X | = | - 7148497.5 |
