( | X | − | 9 | ) | ÷ | ( | 98 | − | 9 | X | ) | = | 4 |
Multiply both sides of the equation by: | ( | 98 | − | 9 | X | ) |
( | X | − | 9 | ) | = | 4 | ( | 98 | − | 9 | X | ) |
X | − | 9 | = | 4 | ( | 98 | − | 9 | X | ) |
X | − | 9 | = | 4 | × | 98 | − | 4 | × | 9 | X |
X | − | 9 | = | 392 | − | 36 | X |
X | + | 36 | X | = | 392 | + | 9 |
37 | X | = | 392 | + | 9 |
37 | X | = | 401 |
X | = | 401 | ÷ | 37 |
= | 401 | × | 1 37 |
X | = | 401 37 |
X | = | 10.837838 |
