[ 1/1 Equation]
Work: Find the solution of equation 12.3c = （3.4+c）×7.92 .
Question type: Equation
Solution:Original question:
123 10 | c | = | ( | 17 5 | + | c | ) | × | 198 25 |
| Right side of the equation = | 17 5 | × | 198 25 | + | c | × | 198 25 |
| = | 3366 125 | + | c | × | 198 25 |
123 10 | c | = | 3366 125 | + | 198 25 | c |
Transposition :
123 10 | c | − | 198 25 | c | = | 3366 125 |
Combine the items on the left of the equation:
219 50 | c | = | 3366 125 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 3366 125 | ÷ | 219 50 |
| = | 3366 125 | × | 50 219 |
| = | 1122 5 | × | 2 73 |
We obtained :
| c | = | 2244 365 |
Convert the result to decimal form :
| c | = | 6.147945 |
