Solve for x.

8x=4x-32

Subtract 4x from both sides.

4x=-32

Divide by 4 on both sides.

x=-8

answer: x=-8

Answer:

$x=\sqrt{\frac{7(4+\sqrt{15})}{2}} $

Step-by-step explanation:

From the way it is written, the x is outside the square root. I will rewrite it as:

x\sqrt{5} =x\sqrt{3} +\sqrt{7}

x\sqrt{5}-x\sqrt{3}=\sqrt{7}

x(\sqrt{5} - \sqrt{3} )=\sqrt{7}

$x= \frac{\sqrt{7} }{\sqrt{5} - \sqrt{3}} \implies \frac{\sqrt{7}(\sqrt{5} + \sqrt{3}) }{2}  $

$x=\frac{1}{2} \sqrt{7} (\sqrt{5} + \sqrt{3} )$

$x=\frac{\sqrt{35}}{2} +\frac{ \sqrt{21}}{2} $

$x=\frac{\sqrt{35}+\sqrt{21}}{2} $

Multiply denominator and numerator by 3

$x=\frac{3\sqrt{35}+3 \sqrt{21}}{6} $

Factor \sqrt{3}

\sqrt{3} (\sqrt{105}+3 \sqrt{7})

$x=\frac{\sqrt{3} (\sqrt{105}+3 \sqrt{7})}{6} $

Divide denominator and numerator by \sqrt{3}

$x=\frac{\sqrt{105}+3 \sqrt{7}}{2\sqrt{3} } $

Let's rewrite it again

$x=\frac{\sqrt{ (\sqrt{105}+3 \sqrt{7})^2}}{\sqrt{12} } $

$x=\sqrt{ \frac{1}{12} \cdot (\sqrt{105}+3 \sqrt{7})^2}$

It is already in the form $\sqrt{\frac{a}{b} } $

Expanding the perfect square, we have

63+42\sqrt{15}+105

$\frac{63}{12} +\frac{42\sqrt{15}}{12} +\frac{105}{12} $

$\frac{21}{4} +\frac{7\sqrt{15}}{2} +\frac{35}{4} $

Factor $\frac{7}{2} $

$\frac{7}{2} (4+\sqrt{15} )$

Therefore,

$x=\sqrt{\frac{7}{2} \left(4+\sqrt{15}   \right)} $

$x=\sqrt{\frac{7(4+\sqrt{15})}{2}} $
