120 | ÷ | x | − | 20 | = | ( | 120 | − | 1 2 | x | ) | ÷ | ( | 3 2 | x | ) |
Multiply both sides of the equation by: | x | , | ( | 3 2 | × | 1 | ) |
120 | ( | 3 2 | × | 1 | ) | − | 20 | x | ( | 3 2 | × | 1 | ) | = | ( | 120 | − | 1 2 | x | ) | × | 1 |
120 | × | 3 2 | × | 1 | − | 20 | x | ( | 3 2 | × | 1 | ) | = | ( | 120 | − | 1 2 | x | ) | × | 1 |
120 | × | 3 2 | × | 1 | − | 20 | x | ( | 3 2 | × | 1 | ) | = | 120 | × | 1 | − | 1 2 | x | × | 1 |
180 | − | 20 | x | ( | 3 2 | × | 1 | ) | = | 120 | − | 1 2 | x |
180 | − | 20 | x | × | 3 2 | × | 1 | = | 120 | − | 1 2 | x |
180 | − | 30 | x | = | 120 | − | 1 2 | x |
- | 30 | x | + | 1 2 | x | = | 120 | − | 180 |
- | 59 2 | x | = | 120 | − | 180 |
- | 59 2 | x | = | - | 60 |
60 | = | 59 2 | x |
59 2 | x | = | 60 |
x | = | 60 | ÷ | 59 2 |
= | 60 | × | 2 59 |
x | = | 120 59 |
x | = | 2.033898 |
