Work: Find the solution of equation 11.93×c = （3.4+c）×7.98 .
Question type: Equation
Solution:Original question:
1193 100 | c | = | ( | 17 5 | + | c | ) | × | 399 50 |
| Right side of the equation = | 17 5 | × | 399 50 | + | c | × | 399 50 |
| = | 6783 250 | + | c | × | 399 50 |
1193 100 | c | = | 6783 250 | + | 399 50 | c |
Transposition :
1193 100 | c | − | 399 50 | c | = | 6783 250 |
Combine the items on the left of the equation:
79 20 | c | = | 6783 250 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 6783 250 | ÷ | 79 20 |
| = | 6783 250 | × | 20 79 |
| = | 6783 25 | × | 2 79 |
We obtained :
| c | = | 13566 1975 |
Convert the result to decimal form :
| c | = | 6.868861 |
