fx=gx
Multiply both sides of the equation by gx.
xf=gx
The equation is in standard form.
\frac{xf}{x}=\frac{gx}{x}
Divide both sides by x.
f=\frac{gx}{x}
Dividing by x undoes the multiplication by x.
f=g
Divide gx by x.
fx=gx
Variable g cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by gx.
gx=fx
Swap sides so that all variable terms are on the left hand side.
xg=fx
The equation is in standard form.
\frac{xg}{x}=\frac{fx}{x}
Divide both sides by x.
g=\frac{fx}{x}
Dividing by x undoes the multiplication by x.
g=f
Divide fx by x.
g=f\text{, }g\neq 0
Variable g cannot be equal to 0.
