xF=2x+15
The equation is in standard form.
\frac{xF}{x}=\frac{2x+15}{x}
Divide both sides by x.
F=\frac{2x+15}{x}
Dividing by x undoes the multiplication by x.
F=2+\frac{15}{x}
Divide 2x+15 by x.
Fx-2x=15
Subtract 2x from both sides.
\left(F-2\right)x=15
Combine all terms containing x.
\frac{\left(F-2\right)x}{F-2}=\frac{15}{F-2}
Divide both sides by F-2.
x=\frac{15}{F-2}
Dividing by F-2 undoes the multiplication by F-2.
