20xy=20
Multiply 4 and 5 to get 20.
20yx=20
The equation is in standard form.
\frac{20yx}{20y}=\frac{20}{20y}
Divide both sides by 20y.
x=\frac{20}{20y}
Dividing by 20y undoes the multiplication by 20y.
x=\frac{1}{y}
Divide 20 by 20y.
20xy=20
Multiply 4 and 5 to get 20.
\frac{20xy}{20x}=\frac{20}{20x}
Divide both sides by 20x.
y=\frac{20}{20x}
Dividing by 20x undoes the multiplication by 20x.
y=\frac{1}{x}
Divide 20 by 20x.
