Σx=8-2
Subtract 2 from both sides.
Σx=6
Subtract 2 from 8 to get 6.
\frac{Σx}{Σ}=\frac{6}{Σ}
Divide both sides by Σ.
x=\frac{6}{Σ}
Dividing by Σ undoes the multiplication by Σ.
Σx=8-2
Subtract 2 from both sides.
Σx=6
Subtract 2 from 8 to get 6.
xΣ=6
The equation is in standard form.
\frac{xΣ}{x}=\frac{6}{x}
Divide both sides by x.
Σ=\frac{6}{x}
Dividing by x undoes the multiplication by x.
