[ 1/1 Equation]
Work: Find the solution of equation 0.3x+15 = 0.384*（x+10 ) .
Question type: Equation
Solution:Original question:
3 10 | x | + | 15 | = | 48 125 | ( | x | + | 10 | ) |
| Right side of the equation = | 48 125 | x | + | 48 125 | × | 10 |
| = | 48 125 | x | + | 96 25 |
3 10 | x | + | 15 | = | 48 125 | x | + | 96 25 |
Transposition :
3 10 | x | − | 48 125 | x | = | 96 25 | − | 15 |
Combine the items on the left of the equation:
| - | 21 250 | x | = | 96 25 | − | 15 |
Combine the items on the right of the equation:
| - | 21 250 | x | = | - | 279 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
279 25 | = | 21 250 | 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 :
21 250 | x | = | 279 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 279 25 | ÷ | 21 250 |
| = | 279 25 | × | 250 21 |
| = | 93 | × | 10 7 |
We obtained :
| x | = | 930 7 |
Convert the result to decimal form :
| x | = | 132.857143 |
