Work: Find the solution of equation (i-7%)/(8%-7%) = 13.73 .
Question type: Equation
Solution:Original question:
| ( | i | − | 7 100 | ) | ÷ | ( | 8 100 | − | 7 100 | ) | = | 1373 100 |
| Multiply both sides of the equation by: | ( | 8 100 | − | 7 100 | ) |
| ( | i | − | 7 100 | ) | = | 1373 100 | ( | 8 100 | − | 7 100 | ) |
| i | − | 7 100 | = | 1373 100 | ( | 8 100 | − | 7 100 | ) |
| i | − | 7 100 | = | 1373 100 | × | 8 100 | − | 1373 100 | × | 7 100 |
| i | − | 7 100 | = | 1373 1250 | − | 9611 10000 |
| i | − | 7 100 | = | 1373 10000 |
Transposition :
| i | = | 1373 10000 | + | 7 100 |
Combine the items on the right of the equation:
| i | = | 2073 10000 |
This is the solution of the equation.
