1 | + | ( | 16 5 | − | 1 | ) | ÷ | ( | 16 5 | X | + | 1 | ) | = | 0 |
Multiply both sides of the equation by: | ( | 16 5 | X | + | 1 | ) |
1 | ( | 16 5 | X | + | 1 | ) | + | ( | 16 5 | − | 1 | ) | = | 0 |
1 | × | 16 5 | X | + | 1 | × | 1 | + | ( | 16 5 | − | 1 | ) | = | 0 |
16 5 | X | + | 1 | + | ( | 16 5 | − | 1 | ) | = | 0 |
16 5 | X | + | 1 | + | 16 5 | − | 1 | = | 0 |
16 5 | X | + | 16 5 | = | 0 |
16 5 | X | = | 0 | − | 16 5 |
16 5 | X | = | - | 16 5 |
X | = | - | 16 5 | ÷ | 16 5 |
= | - | 16 5 | × | 5 16 |
= | - | 1 | × | 1 |
X | = | - | 1 |
