[ 1/1 Equation]
Work: Find the solution of equation 13.11c = （3+c）×7.92 .
Question type: Equation
Solution:Original question:
1311 100 | c | = | ( | 3 | + | c | ) | × | 198 25 |
| Right side of the equation = | 3 | × | 198 25 | + | c | × | 198 25 |
| = | 594 25 | + | c | × | 198 25 |
1311 100 | c | = | 594 25 | + | 198 25 | c |
Transposition :
1311 100 | c | − | 198 25 | c | = | 594 25 |
Combine the items on the left of the equation:
519 100 | c | = | 594 25 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 594 25 | ÷ | 519 100 |
| = | 594 25 | × | 100 519 |
| = | 198 | × | 4 173 |
We obtained :
| c | = | 792 173 |
Convert the result to decimal form :
| c | = | 4.578035 |
