3600 | ÷ | x | − | 3600 | ÷ | ( | x | + | 20 | ) | = | 10 |
Multiply both sides of the equation by: | x |
3600 | − | 3600 | ÷ | ( | x | + | 20 | ) | × | x | = | 10 | x |
Multiply both sides of the equation by: | ( | x | + | 20 | ) |
3600 | ( | x | + | 20 | ) | − | 3600 | x | = | 10 | x | ( | x | + | 20 | ) |
3600 | x | + | 3600 | × | 20 | − | 3600 | x | = | 10 | x | ( | x | + | 20 | ) |
3600 | x | + | 3600 | × | 20 | − | 3600 | x | = | 10 | x | x | + | 10 | x | × | 20 |
3600 | x | + | 72000 | − | 3600 | x | = | 10 | x | x | + | 200 | x |
0 | x | + | 72000 | = | 10 | x | x | + | 200 | x |
