xP=vz
The equation is in standard form.
\frac{xP}{x}=\frac{vz}{x}
Divide both sides by x.
P=\frac{vz}{x}
Dividing by x undoes the multiplication by x.
vz=Px
Swap sides so that all variable terms are on the left hand side.
zv=Px
The equation is in standard form.
\frac{zv}{z}=\frac{Px}{z}
Divide both sides by z.
v=\frac{Px}{z}
Dividing by z undoes the multiplication by z.
