Work: Find the solution of equation 56×7.88+12.08c = （56+c）×7.98 .
Question type: Equation
Solution:Original question:
| 56 | × | 197 25 | + | 302 25 | c | = | ( | 56 | + | c | ) | × | 399 50 |
| Left side of the equation = | 11032 25 | + | 302 25 | c |
11032 25 | + | 302 25 | c | = | ( | 56 | + | c | ) | × | 399 50 |
| Right side of the equation = | 56 | × | 399 50 | + | c | × | 399 50 |
| = | 11172 25 | + | c | × | 399 50 |
11032 25 | + | 302 25 | c | = | 11172 25 | + | 399 50 | c |
Transposition :
302 25 | c | − | 399 50 | c | = | 11172 25 | − | 11032 25 |
Combine the items on the left of the equation:
41 10 | c | = | 11172 25 | − | 11032 25 |
Combine the items on the right of the equation:
41 10 | c | = | 28 5 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 28 5 | ÷ | 41 10 |
| = | 28 5 | × | 10 41 |
| = | 28 | × | 2 41 |
We obtained :
| c | = | 56 41 |
Convert the result to decimal form :
| c | = | 1.365854 |
