10 | + | ( | 2400 | − | 10 | x | ) | ÷ | ( | x | + | 30 | ) | = | 2400 | ÷ | x | − | 2 |
Multiply both sides of the equation by: | ( | x | + | 30 | ) | , | x |
10 | ( | x | + | 30 | ) | x | + | ( | 2400 | − | 10 | x | ) | x | = | 2400 | ( | x | + | 30 | ) | − | 2 | ( | x | + | 30 | ) | x |
10 | x | x | + | 10 | × | 30 | x | + | ( | 2400 | − | 10 | x | ) | x | = | 2400 | ( | x | + | 30 | ) | − | 2 | ( | x | + | 30 | ) | x |
10 | x | x | + | 10 | × | 30 | x | + | ( | 2400 | − | 10 | x | ) | x | = | 2400 | x | + | 2400 | × | 30 | − | 2 | ( | x | + | 30 | ) | x |
10 | x | x | + | 300 | x | + | ( | 2400 | − | 10 | x | ) | x | = | 2400 | x | + | 72000 | − | 2 | ( | x | + | 30 | ) | x |
10 | x | x | + | 300 | x | + | 2400 | x | − | 10 | x | x | = | 2400 | x | + | 72000 | − | 2 | ( | x | + | 30 | ) | x |
10 | x | x | + | 300 | x | + | 2400 | x | − | 10 | x | x | = | 2400 | x | + | 72000 | − | 2 | x | x | − | 2 | × | 30 | x |
10 | x | x | + | 300 | x | + | 2400 | x | − | 10 | x | x | = | 2400 | x | + | 72000 | − | 2 | x | x | − | 60 | x |
10 | x | x | + | 2700 | x | − | 10 | x | x | = | 2340 | x | + | 72000 | − | 2 | x | x |
