Work: Find the solution of equation （172.04-X）*0.1+X = 140.25 .
Question type: Equation
Solution:Original question:
| ( | 4301 25 | − | X | ) | × | 1 10 | + | X | = | 561 4 |
| Left side of the equation = | 4301 25 | × | 1 10 | − | X | × | 1 10 | + | X |
| = | 4301 250 | − | X | × | 1 10 | + | X |
| = | 4301 250 | + | 9 10 | X |
4301 250 | + | 9 10 | X | = | 561 4 |
Transposition :
9 10 | X | = | 561 4 | − | 4301 250 |
Combine the items on the right of the equation:
9 10 | X | = | 61523 500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 61523 500 | ÷ | 9 10 |
| = | 61523 500 | × | 10 9 |
| = | 61523 50 | × | 1 9 |
We obtained :
| X | = | 61523 450 |
Convert the result to decimal form :
| X | = | 136.717778 |
