$x = - \frac{98}{27}$ and $y = - \frac{31}{27}$
#### Explanation:
$3 \cdot \left(- 2 x - 5 y\right) + 2 \cdot \left(3 x - 6 y\right) = 3 \cdot 13 + 2 \cdot \left(- 4\right)$

http://www.irohabook.com/logarithm-properties | # Logarithm Properties – Product & Quotient Rule
The most important logarithm properties are product and quotient rules. Many logarithm formulas are derived from these rules.
## Formula
(Product Rule) $\log_a xy = \log_a x + \log_a y$
(Quotient Rule) $\log_a \dfrac{ x }{ y } = \log_a x - \log_a y$
In particular
