[ 1/1 Equation]
Work: Find the solution of equation X-(5+(X-100)*0.1) = 266.97 .
Question type: Equation
Solution:Original question:
| X | − | ( | 5 | + | ( | X | − | 100 | ) | × | 1 10 | ) | = | 26697 100 |
| Left side of the equation = | X | − | 5 | − | ( | X | − | 100 | ) | × | 1 10 |
| = | X | − | 5 | − | X | × | 1 10 | + | 100 | × | 1 10 |
| = | X | − | 5 | − | X | × | 1 10 | + | 10 |
| = | 9 10 | X | + | 5 |
9 10 | X | + | 5 | = | 26697 100 |
Transposition :
9 10 | X | = | 26697 100 | − | 5 |
Combine the items on the right of the equation:
9 10 | X | = | 26197 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 26197 100 | ÷ | 9 10 |
| = | 26197 100 | × | 10 9 |
| = | 26197 10 | × | 1 9 |
We obtained :
| X | = | 26197 90 |
Convert the result to decimal form :
| X | = | 291.077778 |
