x_{4}x_{2}=2
The equation is in standard form.
\frac{x_{4}x_{2}}{x_{4}}=\frac{2}{x_{4}}
Divide both sides by x_{4}.
x_{2}=\frac{2}{x_{4}}
Dividing by x_{4} undoes the multiplication by x_{4}.
x_{2}x_{4}=2
The equation is in standard form.
\frac{x_{2}x_{4}}{x_{2}}=\frac{2}{x_{2}}
Divide both sides by x_{2}.
x_{4}=\frac{2}{x_{2}}
Dividing by x_{2} undoes the multiplication by x_{2}.
