Work: Find the solution of equation 0.86X+7.4（95-X） = 0.238 .
Question type: Equation
Solution:Original question:
43 50 | X | + | 37 5 | ( | 95 | − | X | ) | = | 119 500 |
| Left side of the equation = | 43 50 | X | + | 37 5 | × | 95 | − | 37 5 | X |
| = | 43 50 | X | + | 703 | − | 37 5 | X |
| = | - | 327 50 | X | + | 703 |
| - | 327 50 | X | + | 703 | = | 119 500 |
Transposition :
| - | 327 50 | X | = | 119 500 | − | 703 |
Combine the items on the right of the equation:
| - | 327 50 | X | = | - | 351381 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
351381 500 | = | 327 50 | 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 :
327 50 | X | = | 351381 500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 351381 500 | ÷ | 327 50 |
| = | 351381 500 | × | 50 327 |
| = | 117127 10 | × | 1 109 |
We obtained :
| X | = | 117127 1090 |
Convert the result to decimal form :
| X | = | 107.455963 |
