Work: Find the solution of equation 7.92（c+3.3） = 13.16 .
Question type: Equation
Solution:Original question:
198 25 | ( | c | + | 33 10 | ) | = | 329 25 |
| Left side of the equation = | 198 25 | c | + | 198 25 | × | 33 10 |
| = | 198 25 | c | + | 3267 125 |
198 25 | c | + | 3267 125 | = | 329 25 |
Transposition :
198 25 | c | = | 329 25 | − | 3267 125 |
Combine the items on the right of the equation:
198 25 | c | = | - | 1622 125 |
The coefficient of the unknown number is reduced to 1 :
| c | = | - | 1622 125 | ÷ | 198 25 |
| = | - | 1622 125 | × | 25 198 |
| = | - | 811 5 | × | 1 99 |
We obtained :
| c | = | - | 811 495 |
Convert the result to decimal form :
| c | = | - 1.638384 |
