v\sqrt{7}=5-23
Subtract 23 from both sides.
v\sqrt{7}=-18
Subtract 23 from 5 to get -18.
\sqrt{7}v=-18
The equation is in standard form.
\frac{\sqrt{7}v}{\sqrt{7}}=-\frac{18}{\sqrt{7}}
Divide both sides by \sqrt{7}.
v=-\frac{18}{\sqrt{7}}
Dividing by \sqrt{7} undoes the multiplication by \sqrt{7}.
v=-\frac{18\sqrt{7}}{7}
Divide -18 by \sqrt{7}.
