Work: Find the solution of equation 12.1c = （3.5+c）×7.92 .
Question type: Equation
Solution:Original question:
121 10 | c | = | ( | 7 2 | + | c | ) | × | 198 25 |
| Right side of the equation = | 7 2 | × | 198 25 | + | c | × | 198 25 |
| = | 693 25 | + | c | × | 198 25 |
121 10 | c | = | 693 25 | + | 198 25 | c |
Transposition :
121 10 | c | − | 198 25 | c | = | 693 25 |
Combine the items on the left of the equation:
209 50 | c | = | 693 25 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 693 25 | ÷ | 209 50 |
| = | 693 25 | × | 50 209 |
| = | 63 | × | 2 19 |
We obtained :
| c | = | 126 19 |
Convert the result to decimal form :
| c | = | 6.631579 |
