Vx=3x-14-6
Subtract 6 from both sides.
Vx=3x-20
Subtract 6 from -14 to get -20.
xV=3x-20
The equation is in standard form.
\frac{xV}{x}=\frac{3x-20}{x}
Divide both sides by x.
V=\frac{3x-20}{x}
Dividing by x undoes the multiplication by x.
V=3-\frac{20}{x}
Divide 3x-20 by x.
Vx+6-3x=-14
Subtract 3x from both sides.
Vx-3x=-14-6
Subtract 6 from both sides.
Vx-3x=-20
Subtract 6 from -14 to get -20.
\left(V-3\right)x=-20
Combine all terms containing x.
\frac{\left(V-3\right)x}{V-3}=-\frac{20}{V-3}
Divide both sides by V-3.
x=-\frac{20}{V-3}
Dividing by V-3 undoes the multiplication by V-3.
