( | x | − | 60 | ) | ÷ | ( | x | + | 60 | ) | = | 2 | ÷ | 3 |
Multiply both sides of the equation by: | ( | x | + | 60 | ) |
( | x | − | 60 | ) | = | 2 | ÷ | 3 | × | ( | x | + | 60 | ) |
x | − | 60 | = | 2 | ÷ | 3 | × | ( | x | + | 60 | ) |
x | − | 60 | = | 2 | ÷ | 3 | × | x | + | 2 | ÷ | 3 | × | 60 |
x | − | 60 | = | 2 3 | x | + | 40 |
x | − | 2 3 | x | = | 40 | + | 60 |
1 3 | x | = | 40 | + | 60 |
1 3 | x | = | 100 |
x | = | 100 | ÷ | 1 3 |
= | 100 | × | 3 |
x | = | 300 |
