Work: Find the solution of equation 29.952*[1+(0.04x0.50)] = 0 .
Question type: Equation
Solution:Original question:
3744 125 | ( | 1 | + | ( | 1 25 | x | × | 1 2 | ) | ) | = | 0 |
| Left side of the equation = | 3744 125 | × | 1 | + | 3744 125 | ( | 1 25 | x | × | 1 2 | ) |
| = | 3744 125 | + | 3744 125 | ( | 1 25 | x | × | 1 2 | ) |
| = | 3744 125 | + | 3744 125 | × | 1 25 | x | × | 1 2 |
| = | 3744 125 | + | 1872 3125 | x |
3744 125 | + | 1872 3125 | x | = | 0 |
Transposition :
1872 3125 | x | = | 0 | − | 3744 125 |
Combine the items on the right of the equation:
1872 3125 | x | = | - | 3744 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 3744 125 | ÷ | 1872 3125 |
| = | - | 3744 125 | × | 3125 1872 |
| = | - | 2 | × | 25 |
We obtained :
| x | = | - | 50 |
