## Mathhelp346 2 years ago PLEASE HELP!! : log base 7 3x - log base 7 9x + log base 7 6y

1. Mathhelp346

$\log_{7}3x -\log_{7}9x+\log_{7}6y$

2. abb0t

$\log_ab-\log_ac= \log_a \frac{ b }{ c }$ similarly $\log_ab + \log_ac = \log_abc$

3. Mathhelp346

Yes

4. abb0t

5. Mathhelp346

$\log_{7}\frac{ 1 }{ 3 }x +\log_{7}6y$

6. Mathhelp346

But then what do I do with the x and y?
