n=\left(n+3\right)\sqrt{\frac{3}{8}}
Variable n cannot be equal to -3 since division by zero is not defined. Multiply both sides of the equation by n+3.
n=\left(n+3\right)\times \frac{\sqrt{3}}{\sqrt{8}}
Rewrite the square root of the division \sqrt{\frac{3}{8}} as the division of square roots \frac{\sqrt{3}}{\sqrt{8}}.
n=\left(n+3\right)\times \frac{\sqrt{3}}{2\sqrt{2}}
Factor 8=2^{2}\times 2. Rewrite the square root of the product \sqrt{2^{2}\times 2} as the product of square roots \sqrt{2^{2}}\sqrt{2}. Take the square root of 2^{2}.
n=\left(n+3\right)\times \frac{\sqrt{3}\sqrt{2}}{2\left(\sqrt{2}\right)^{2}}
Rationalize the denominator of \frac{\sqrt{3}}{2\sqrt{2}} by multiplying numerator and denominator by \sqrt{2}.
n=\left(n+3\right)\times \frac{\sqrt{3}\sqrt{2}}{2\times 2}
The square of \sqrt{2} is 2.
n=\left(n+3\right)\times \frac{\sqrt{6}}{2\times 2}
To multiply \sqrt{3} and \sqrt{2}, multiply the numbers under the square root.
n=\left(n+3\right)\times \frac{\sqrt{6}}{4}
Multiply 2 and 2 to get 4.
n=\frac{\left(n+3\right)\sqrt{6}}{4}
Express \left(n+3\right)\times \frac{\sqrt{6}}{4} as a single fraction.
n=\frac{n\sqrt{6}+3\sqrt{6}}{4}
Use the distributive property to multiply n+3 by \sqrt{6}.
n-\frac{n\sqrt{6}+3\sqrt{6}}{4}=0
Subtract \frac{n\sqrt{6}+3\sqrt{6}}{4} from both sides.
4n-\left(n\sqrt{6}+3\sqrt{6}\right)=0
Multiply both sides of the equation by 4.
4n-n\sqrt{6}-3\sqrt{6}=0
To find the opposite of n\sqrt{6}+3\sqrt{6}, find the opposite of each term.
4n-n\sqrt{6}=3\sqrt{6}
Add 3\sqrt{6} to both sides. Anything plus zero gives itself.
\left(4-\sqrt{6}\right)n=3\sqrt{6}
Combine all terms containing n.
\frac{\left(4-\sqrt{6}\right)n}{4-\sqrt{6}}=\frac{3\sqrt{6}}{4-\sqrt{6}}
Divide both sides by 4-\sqrt{6}.
n=\frac{3\sqrt{6}}{4-\sqrt{6}}
Dividing by 4-\sqrt{6} undoes the multiplication by 4-\sqrt{6}.
n=\frac{6\sqrt{6}+9}{5}
Divide 3\sqrt{6} by 4-\sqrt{6}.
