( | 2200 | − | x | ) | ÷ | x | = | - | 77 100 |
Multiply both sides of the equation by: | x |
( | 2200 | − | x | ) | = | - | 77 100 | x |
2200 | − | x | = | - | 77 100 | x |
- | x | + | 77 100 | x | = | - | 2200 |
- | 23 100 | x | = | - | 2200 |
2200 | = | 23 100 | x |
23 100 | x | = | 2200 |
x | = | 2200 | ÷ | 23 100 |
= | 2200 | × | 100 23 |
x | = | 220000 23 |
x | = | 9565.217391 |
