Σ_{3}x=4
The equation is in standard form.
\frac{Σ_{3}x}{Σ_{3}}=\frac{4}{Σ_{3}}
Divide both sides by Σ_{3}.
x=\frac{4}{Σ_{3}}
Dividing by Σ_{3} undoes the multiplication by Σ_{3}.
xΣ_{3}=4
The equation is in standard form.
\frac{xΣ_{3}}{x}=\frac{4}{x}
Divide both sides by x.
Σ_{3}=\frac{4}{x}
Dividing by x undoes the multiplication by x.
