Work: Find the solution of equation 25.09×6.24+13.08c = （25.09+c）×7.92 .
Question type: Equation
Solution:Original question:
2509 100 | × | 156 25 | + | 327 25 | c | = | ( | 2509 100 | + | c | ) | × | 198 25 |
| Left side of the equation = | 97851 625 | + | 327 25 | c |
97851 625 | + | 327 25 | c | = | ( | 2509 100 | + | c | ) | × | 198 25 |
| Right side of the equation = | 2509 100 | × | 198 25 | + | c | × | 198 25 |
| = | 248391 1250 | + | c | × | 198 25 |
97851 625 | + | 327 25 | c | = | 248391 1250 | + | 198 25 | c |
Transposition :
327 25 | c | − | 198 25 | c | = | 248391 1250 | − | 97851 625 |
Combine the items on the left of the equation:
129 25 | c | = | 248391 1250 | − | 97851 625 |
Combine the items on the right of the equation:
129 25 | c | = | 52689 1250 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 52689 1250 | ÷ | 129 25 |
| = | 52689 1250 | × | 25 129 |
| = | 17563 50 | × | 1 43 |
We obtained :
| c | = | 17563 2150 |
Convert the result to decimal form :
| c | = | 8.168837 |
