☆2 equations
[ 1/2 Equation]
Work: Find the solution of equation 0.12X = 0 .
Question type: Equation
Solution:Original question:
3 25 | X | = | 0 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 0 | ÷ | 3 25 |
| = | 0 | × | 25 3 |
We obtained :
| X | = | 0 |
[ 2/2 Equation]
Work: Find the solution of equation (0.4x)*0.92+4000 = X*0.55 .
Question type: Equation
Solution:Original question:
| ( | 2 5 | x | ) | × | 23 25 | + | 4000 | = | x | × | 11 20 |
| Left side of the equation = | 2 5 | x | × | 23 25 | + | 4000 |
| = | 46 125 | x | + | 4000 |
46 125 | x | + | 4000 | = | x | × | 11 20 |
Transposition :
46 125 | x | − | 11 20 | x | = | - | 4000 |
Combine the items on the left of the equation:
| - | 91 500 | x | = | - | 4000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 4000 | = | 91 500 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
91 500 | x | = | 4000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4000 | ÷ | 91 500 |
| = | 4000 | × | 500 91 |
We obtained :
| x | = | 2000000 91 |
Convert the result to decimal form :
| x | = | 21978.021978 |
