Work: Find the solution of equation x-0.2x-0.05x-3 = 23.88+0.2*23.88 .
Question type: Equation
Solution:Original question:
| x | − | 1 5 | x | − | 1 20 | x | − | 3 | = | 597 25 | + | 1 5 | × | 597 25 |
| Left side of the equation = | 3 4 | x | − | 3 |
3 4 | x | − | 3 | = | 597 25 | + | 1 5 | × | 597 25 |
| Right side of the equation = | 597 25 | + | 597 125 |
| = | 3582 125 |
3 4 | x | − | 3 | = | 3582 125 |
Transposition :
3 4 | x | = | 3582 125 | + | 3 |
Combine the items on the right of the equation:
3 4 | x | = | 3957 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3957 125 | ÷ | 3 4 |
| = | 3957 125 | × | 4 3 |
| = | 1319 125 | × | 4 |
We obtained :
| x | = | 5276 125 |
Convert the result to decimal form :
| x | = | 42.208 |
