yP_{x}=4
The equation is in standard form.
\frac{yP_{x}}{y}=\frac{4}{y}
Divide both sides by y.
P_{x}=\frac{4}{y}
Dividing by y undoes the multiplication by y.
P_{x}y=4
The equation is in standard form.
\frac{P_{x}y}{P_{x}}=\frac{4}{P_{x}}
Divide both sides by P_{x}.
y=\frac{4}{P_{x}}
Dividing by P_{x} undoes the multiplication by P_{x}.
