40=\frac{x}{\frac{\sqrt{3}}{2}}
Anything divided by one gives itself.
40=\frac{x\times 2}{\sqrt{3}}
Divide x by \frac{\sqrt{3}}{2} by multiplying x by the reciprocal of \frac{\sqrt{3}}{2}.
40=\frac{x\times 2\sqrt{3}}{\left(\sqrt{3}\right)^{2}}
Rationalize the denominator of \frac{x\times 2}{\sqrt{3}} by multiplying numerator and denominator by \sqrt{3}.
40=\frac{x\times 2\sqrt{3}}{3}
The square of \sqrt{3} is 3.
\frac{x\times 2\sqrt{3}}{3}=40
Swap sides so that all variable terms are on the left hand side.
x\times 2\sqrt{3}=40\times 3
Multiply both sides by 3.
x\times 2\sqrt{3}=120
Multiply 40 and 3 to get 120.
2\sqrt{3}x=120
The equation is in standard form.
\frac{2\sqrt{3}x}{2\sqrt{3}}=\frac{120}{2\sqrt{3}}
Divide both sides by 2\sqrt{3}.
x=\frac{120}{2\sqrt{3}}
Dividing by 2\sqrt{3} undoes the multiplication by 2\sqrt{3}.
x=20\sqrt{3}
Divide 120 by 2\sqrt{3}.
