yd=2x
The equation is in standard form.
\frac{yd}{y}=\frac{2x}{y}
Divide both sides by y.
d=\frac{2x}{y}
Dividing by y undoes the multiplication by y.
yd=2x
The equation is in standard form.
\frac{yd}{y}=\frac{2x}{y}
Divide both sides by y.
d=\frac{2x}{y}
Dividing by y undoes the multiplication by y.
2x=dy
Swap sides so that all variable terms are on the left hand side.
\frac{2x}{2}=\frac{dy}{2}
Divide both sides by 2.
x=\frac{dy}{2}
Dividing by 2 undoes the multiplication by 2.
