[ 1/1 Equation]
Work: Find the solution of equation 12.1c = （3.3+c）×7.93 .
Question type: Equation
Solution:Original question:
121 10 | c | = | ( | 33 10 | + | c | ) | × | 793 100 |
| Right side of the equation = | 33 10 | × | 793 100 | + | c | × | 793 100 |
| = | 26169 1000 | + | c | × | 793 100 |
121 10 | c | = | 26169 1000 | + | 793 100 | c |
Transposition :
121 10 | c | − | 793 100 | c | = | 26169 1000 |
Combine the items on the left of the equation:
417 100 | c | = | 26169 1000 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 26169 1000 | ÷ | 417 100 |
| = | 26169 1000 | × | 100 417 |
| = | 8723 10 | × | 1 139 |
We obtained :
| c | = | 8723 1390 |
Convert the result to decimal form :
| c | = | 6.27554 |
