3\left(\frac{\sqrt{3}}{3}+1\right)x=300
Multiply both sides of the equation by 3.
\left(3\times \frac{\sqrt{3}}{3}+3\right)x=300
Use the distributive property to multiply 3 by \frac{\sqrt{3}}{3}+1.
\left(\frac{3\sqrt{3}}{3}+3\right)x=300
Express 3\times \frac{\sqrt{3}}{3} as a single fraction.
\left(\sqrt{3}+3\right)x=300
Cancel out 3 and 3.
\frac{\left(\sqrt{3}+3\right)x}{\sqrt{3}+3}=\frac{300}{\sqrt{3}+3}
Divide both sides by \sqrt{3}+3.
x=\frac{300}{\sqrt{3}+3}
Dividing by \sqrt{3}+3 undoes the multiplication by \sqrt{3}+3.
x=150-50\sqrt{3}
Divide 300 by \sqrt{3}+3.
