[ 1/1 Equation]
Work: Find the solution of equation 13.2c = （3+c）×7.94 .
Question type: Equation
Solution:Original question:
66 5 | c | = | ( | 3 | + | c | ) | × | 397 50 |
| Right side of the equation = | 3 | × | 397 50 | + | c | × | 397 50 |
| = | 1191 50 | + | c | × | 397 50 |
66 5 | c | = | 1191 50 | + | 397 50 | c |
Transposition :
66 5 | c | − | 397 50 | c | = | 1191 50 |
Combine the items on the left of the equation:
263 50 | c | = | 1191 50 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 1191 50 | ÷ | 263 50 |
| = | 1191 50 | × | 50 263 |
| = | 1191 | × | 1 263 |
We obtained :
| c | = | 1191 263 |
Convert the result to decimal form :
| c | = | 4.528517 |
