\left(\frac{1}{4}x\times 5^{\frac{1}{2}}+\frac{3}{4}x\right)\times 2\sqrt{2}=3+\sqrt{5}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\left(\frac{1}{4}x\times 5^{\frac{1}{2}}\times 2+\frac{3}{4}x\times 2\right)\sqrt{2}=3+\sqrt{5}
Use the distributive property to multiply \frac{1}{4}x\times 5^{\frac{1}{2}}+\frac{3}{4}x by 2.
\left(\frac{2}{4}x\times 5^{\frac{1}{2}}+\frac{3}{4}x\times 2\right)\sqrt{2}=3+\sqrt{5}
Multiply \frac{1}{4} and 2 to get \frac{2}{4}.
\left(\frac{1}{2}x\times 5^{\frac{1}{2}}+\frac{3}{4}x\times 2\right)\sqrt{2}=3+\sqrt{5}
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
\left(\frac{1}{2}x\times 5^{\frac{1}{2}}+\frac{3\times 2}{4}x\right)\sqrt{2}=3+\sqrt{5}
Express \frac{3}{4}\times 2 as a single fraction.
\left(\frac{1}{2}x\times 5^{\frac{1}{2}}+\frac{6}{4}x\right)\sqrt{2}=3+\sqrt{5}
Multiply 3 and 2 to get 6.
\left(\frac{1}{2}x\times 5^{\frac{1}{2}}+\frac{3}{2}x\right)\sqrt{2}=3+\sqrt{5}
Reduce the fraction \frac{6}{4} to lowest terms by extracting and canceling out 2.
\frac{1}{2}x\times 5^{\frac{1}{2}}\sqrt{2}+\frac{3}{2}x\sqrt{2}=3+\sqrt{5}
Use the distributive property to multiply \frac{1}{2}x\times 5^{\frac{1}{2}}+\frac{3}{2}x by \sqrt{2}.
\frac{1}{2}\sqrt{2}\sqrt{5}x+\frac{3}{2}\sqrt{2}x=\sqrt{5}+3
Reorder the terms.
\frac{1}{2}\sqrt{10}x+\frac{3}{2}\sqrt{2}x=\sqrt{5}+3
To multiply \sqrt{2} and \sqrt{5}, multiply the numbers under the square root.
\left(\frac{1}{2}\sqrt{10}+\frac{3}{2}\sqrt{2}\right)x=\sqrt{5}+3
Combine all terms containing x.
\frac{\sqrt{10}+3\sqrt{2}}{2}x=\sqrt{5}+3
The equation is in standard form.
\frac{2\times \frac{\sqrt{10}+3\sqrt{2}}{2}x}{\sqrt{10}+3\sqrt{2}}=\frac{2\left(\sqrt{5}+3\right)}{\sqrt{10}+3\sqrt{2}}
Divide both sides by \frac{1}{2}\sqrt{10}+\frac{3}{2}\sqrt{2}.
x=\frac{2\left(\sqrt{5}+3\right)}{\sqrt{10}+3\sqrt{2}}
Dividing by \frac{1}{2}\sqrt{10}+\frac{3}{2}\sqrt{2} undoes the multiplication by \frac{1}{2}\sqrt{10}+\frac{3}{2}\sqrt{2}.
x=\sqrt{2}
Divide 3+\sqrt{5} by \frac{1}{2}\sqrt{10}+\frac{3}{2}\sqrt{2}.
