2\times 4\sqrt{3}=x\sqrt{2}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of x,2.
8\sqrt{3}=x\sqrt{2}
Multiply 2 and 4 to get 8.
x\sqrt{2}=8\sqrt{3}
Swap sides so that all variable terms are on the left hand side.
\sqrt{2}x=8\sqrt{3}
The equation is in standard form.
\frac{\sqrt{2}x}{\sqrt{2}}=\frac{8\sqrt{3}}{\sqrt{2}}
Divide both sides by \sqrt{2}.
x=\frac{8\sqrt{3}}{\sqrt{2}}
Dividing by \sqrt{2} undoes the multiplication by \sqrt{2}.
x=4\sqrt{6}
Divide 8\sqrt{3} by \sqrt{2}.
