ΣF=8
Multiply 2 and 4 to get 8.
\frac{ΣF}{Σ}=\frac{8}{Σ}
Divide both sides by Σ.
F=\frac{8}{Σ}
Dividing by Σ undoes the multiplication by Σ.
ΣF=8
Multiply 2 and 4 to get 8.
FΣ=8
The equation is in standard form.
\frac{FΣ}{F}=\frac{8}{F}
Divide both sides by F.
Σ=\frac{8}{F}
Dividing by F undoes the multiplication by F.
