Work: Find the solution of equation 12.07c = （3.4+c）×7.92 .
Question type: Equation
Solution:Original question:
1207 100 | c | = | ( | 17 5 | + | c | ) | × | 198 25 |
| Right side of the equation = | 17 5 | × | 198 25 | + | c | × | 198 25 |
| = | 3366 125 | + | c | × | 198 25 |
1207 100 | c | = | 3366 125 | + | 198 25 | c |
Transposition :
1207 100 | c | − | 198 25 | c | = | 3366 125 |
Combine the items on the left of the equation:
83 20 | c | = | 3366 125 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 3366 125 | ÷ | 83 20 |
| = | 3366 125 | × | 20 83 |
| = | 3366 25 | × | 4 83 |
We obtained :
| c | = | 13464 2075 |
Convert the result to decimal form :
| c | = | 6.488675 |
