Work: Find the solution of equation 12.09×c = （3.3+c）×7.93 .
Question type: Equation
Solution:Original question:
1209 100 | c | = | ( | 33 10 | + | c | ) | × | 793 100 |
| Right side of the equation = | 33 10 | × | 793 100 | + | c | × | 793 100 |
| = | 26169 1000 | + | c | × | 793 100 |
1209 100 | c | = | 26169 1000 | + | 793 100 | c |
Transposition :
1209 100 | c | − | 793 100 | c | = | 26169 1000 |
Combine the items on the left of the equation:
104 25 | c | = | 26169 1000 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 26169 1000 | ÷ | 104 25 |
| = | 26169 1000 | × | 25 104 |
| = | 26169 40 | × | 1 104 |
We obtained :
| c | = | 26169 4160 |
By reducing fraction, we can get:
| c | = | 2013 320 |
Convert the result to decimal form :
| c | = | 6.290625 |
