Work: Find the solution of equation 255.7×7.94+12.08x = （255.7+x）×7.97 .
Question type: Equation
Solution:Original question:
2557 10 | × | 397 50 | + | 302 25 | x | = | ( | 2557 10 | + | x | ) | × | 797 100 |
| Left side of the equation = | 1015129 500 | + | 302 25 | x |
1015129 500 | + | 302 25 | x | = | ( | 2557 10 | + | x | ) | × | 797 100 |
| Right side of the equation = | 2557 10 | × | 797 100 | + | x | × | 797 100 |
| = | 2037929 1000 | + | x | × | 797 100 |
1015129 500 | + | 302 25 | x | = | 2037929 1000 | + | 797 100 | x |
Transposition :
302 25 | x | − | 797 100 | x | = | 2037929 1000 | − | 1015129 500 |
Combine the items on the left of the equation:
411 100 | x | = | 2037929 1000 | − | 1015129 500 |
Combine the items on the right of the equation:
411 100 | x | = | 7671 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7671 1000 | ÷ | 411 100 |
| = | 7671 1000 | × | 100 411 |
| = | 2557 10 | × | 1 137 |
We obtained :
| x | = | 2557 1370 |
Convert the result to decimal form :
| x | = | 1.866423 |
