Work: Find the solution of equation 12.11c = （3.3+c）×7.98 .
Question type: Equation
Solution:Original question:
1211 100 | c | = | ( | 33 10 | + | c | ) | × | 399 50 |
| Right side of the equation = | 33 10 | × | 399 50 | + | c | × | 399 50 |
| = | 13167 500 | + | c | × | 399 50 |
1211 100 | c | = | 13167 500 | + | 399 50 | c |
Transposition :
1211 100 | c | − | 399 50 | c | = | 13167 500 |
Combine the items on the left of the equation:
413 100 | c | = | 13167 500 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 13167 500 | ÷ | 413 100 |
| = | 13167 500 | × | 100 413 |
| = | 1881 5 | × | 1 59 |
We obtained :
| c | = | 1881 295 |
Convert the result to decimal form :
| c | = | 6.376271 |
