[ 1/1 Equation]
Work: Find the solution of equation 15.21x = 12.96（15.21-x） .
Question type: Equation
Solution:Original question:
1521 100 | x | = | 324 25 | ( | 1521 100 | − | x | ) |
| Right side of the equation = | 324 25 | × | 1521 100 | − | 324 25 | x |
| = | 123201 625 | − | 324 25 | x |
1521 100 | x | = | 123201 625 | − | 324 25 | x |
Transposition :
1521 100 | x | + | 324 25 | x | = | 123201 625 |
Combine the items on the left of the equation:
2817 100 | x | = | 123201 625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 123201 625 | ÷ | 2817 100 |
| = | 123201 625 | × | 100 2817 |
| = | 13689 25 | × | 4 313 |
We obtained :
| x | = | 54756 7825 |
Convert the result to decimal form :
| x | = | 6.997572 |
