Work: Find the solution of equation 28×7.3+11.99c = （28+c）×7.97 .
Question type: Equation
Solution:Original question:
| 28 | × | 73 10 | + | 1199 100 | c | = | ( | 28 | + | c | ) | × | 797 100 |
| Left side of the equation = | 1022 5 | + | 1199 100 | c |
1022 5 | + | 1199 100 | c | = | ( | 28 | + | c | ) | × | 797 100 |
| Right side of the equation = | 28 | × | 797 100 | + | c | × | 797 100 |
| = | 5579 25 | + | c | × | 797 100 |
1022 5 | + | 1199 100 | c | = | 5579 25 | + | 797 100 | c |
Transposition :
1199 100 | c | − | 797 100 | c | = | 5579 25 | − | 1022 5 |
Combine the items on the left of the equation:
201 50 | c | = | 5579 25 | − | 1022 5 |
Combine the items on the right of the equation:
201 50 | c | = | 469 25 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 469 25 | ÷ | 201 50 |
| = | 469 25 | × | 50 201 |
| = | 469 | × | 2 201 |
We obtained :
| c | = | 938 201 |
By reducing fraction, we can get:
| c | = | 14 3 |
Convert the result to decimal form :
| c | = | 4.666667 |
