Work: Find the solution of equation 12.18c = （c+3.5）×7.98 .
Question type: Equation
Solution:Original question:
609 50 | c | = | ( | c | + | 7 2 | ) | × | 399 50 |
| Right side of the equation = | c | × | 399 50 | + | 7 2 | × | 399 50 |
| = | c | × | 399 50 | + | 2793 100 |
609 50 | c | = | 399 50 | c | + | 2793 100 |
Transposition :
609 50 | c | − | 399 50 | c | = | 2793 100 |
Combine the items on the left of the equation:
21 5 | c | = | 2793 100 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 2793 100 | ÷ | 21 5 |
| = | 2793 100 | × | 5 21 |
| = | 133 20 | × | 1 |
We obtained :
| c | = | 133 20 |
Convert the result to decimal form :
| c | = | 6.65 |
