Step-by-step explanation:

-5x+8y=-4

6x-8y=-12 8y and 8x cancel out

x=-16

To solve for y, substitute x=-16 back into the first equation

-5(-16)+8y=-4

80+8y=-4

8y=-84

y=-10.5

Answer: $8\sqrt{6}$

Step-by-step explanation:

$\frac{2^4\sqrt{3}}{\sqrt{2}}$

$2^{\frac{7}{2}}\sqrt{3}$

$2^{\frac{7}{2}}=2^{3+\frac{1}{2}}$

$2^3\cdot \:2^{\frac{1}{2}}$ =

$2^3\sqrt{2}$

= $2^3\sqrt{2}\sqrt{3}$ =

$2^3\sqrt{2\cdot \:3}$

= $2^3\sqrt{6}$

$2^3=8$

Answer- $8\sqrt{6}$
