Work: Find the solution of equation X = 120＋0.05X＋15%＋0.17X/1.17 .
Question type: Equation
Solution:Original question:
| X | = | 120 | + | 1 20 | X | + | 15 100 | + | 17 100 | X | ÷ | 117 100 |
| Right side of the equation = | 120 | + | 1 20 | X | + | 15 100 | + | 17 117 | X |
| = | 2403 20 | + | 457 2340 | X |
| X | = | 2403 20 | + | 457 2340 | X |
Transposition :
| X | − | 457 2340 | X | = | 2403 20 |
Combine the items on the left of the equation:
1883 2340 | X | = | 2403 20 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2403 20 | ÷ | 1883 2340 |
| = | 2403 20 | × | 2340 1883 |
| = | 2403 | × | 117 1883 |
We obtained :
| X | = | 281151 1883 |
Convert the result to decimal form :
| X | = | 149.310143 |
