Work: Find the solution of equation 30×6.08+11.91c = （（c+30）×7.98 ) .
Question type: Equation
Solution:Original question:
| 30 | × | 152 25 | + | 1191 100 | c | = | ( | ( | c | + | 30 | ) | × | 399 50 | ) |
| Left side of the equation = | 912 5 | + | 1191 100 | c |
912 5 | + | 1191 100 | c | = | ( | ( | c | + | 30 | ) | × | 399 50 | ) |
| Right side of the equation = | ( | c | + | 30 | ) | × | 399 50 |
| = | c | × | 399 50 | + | 30 | × | 399 50 |
| = | c | × | 399 50 | + | 1197 5 |
912 5 | + | 1191 100 | c | = | 399 50 | c | + | 1197 5 |
Transposition :
1191 100 | c | − | 399 50 | c | = | 1197 5 | − | 912 5 |
Combine the items on the left of the equation:
393 100 | c | = | 1197 5 | − | 912 5 |
Combine the items on the right of the equation:
393 100 | c | = | 57 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 57 | ÷ | 393 100 |
| = | 57 | × | 100 393 |
| = | 19 | × | 100 131 |
We obtained :
| c | = | 1900 131 |
Convert the result to decimal form :
| c | = | 14.503817 |
