[ 1/1 Equation]
Work: Find the solution of equation 30×6.08+11.91c = （30+c）×7.97 .
Question type: Equation
Solution:Original question:
| 30 | × | 152 25 | + | 1191 100 | c | = | ( | 30 | + | c | ) | × | 797 100 |
| Left side of the equation = | 912 5 | + | 1191 100 | c |
912 5 | + | 1191 100 | c | = | ( | 30 | + | c | ) | × | 797 100 |
| Right side of the equation = | 30 | × | 797 100 | + | c | × | 797 100 |
| = | 2391 10 | + | c | × | 797 100 |
912 5 | + | 1191 100 | c | = | 2391 10 | + | 797 100 | c |
Transposition :
1191 100 | c | − | 797 100 | c | = | 2391 10 | − | 912 5 |
Combine the items on the left of the equation:
197 50 | c | = | 2391 10 | − | 912 5 |
Combine the items on the right of the equation:
197 50 | c | = | 567 10 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 567 10 | ÷ | 197 50 |
| = | 567 10 | × | 50 197 |
| = | 567 | × | 5 197 |
We obtained :
| c | = | 2835 197 |
Convert the result to decimal form :
| c | = | 14.390863 |
