Work: Find the solution of equation 7.92×（c+3.2） = 12.18c .
Question type: Equation
Solution:Original question:
198 25 | ( | c | + | 16 5 | ) | = | 609 50 | c |
| Left side of the equation = | 198 25 | c | + | 198 25 | × | 16 5 |
| = | 198 25 | c | + | 3168 125 |
198 25 | c | + | 3168 125 | = | 609 50 | c |
Transposition :
198 25 | c | − | 609 50 | c | = | - | 3168 125 |
Combine the items on the left of the equation:
| - | 213 50 | c | = | - | 3168 125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3168 125 | = | 213 50 | c |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
213 50 | c | = | 3168 125 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 3168 125 | ÷ | 213 50 |
| = | 3168 125 | × | 50 213 |
| = | 1056 5 | × | 2 71 |
We obtained :
| c | = | 2112 355 |
Convert the result to decimal form :
| c | = | 5.949296 |
