Solve for x
x=-\frac{2}{v^{2}}
v\neq 0
Solve for v (complex solution)
v=-\sqrt{2}ix^{-\frac{1}{2}}
v=\sqrt{2}ix^{-\frac{1}{2}}\text{, }x\neq 0
Solve for v
v=\sqrt{-\frac{2}{x}}
v=-\sqrt{-\frac{2}{x}}\text{, }x<0

8-2v^{2}x=24\times \frac{1}{2}
Multiply both sides of the equation by 8, the least common multiple of 8,2.
8-2v^{2}x=12
Multiply 24 and \frac{1}{2} to get 12.
-2v^{2}x=12-8
Subtract 8 from both sides.
-2v^{2}x=4
Subtract 8 from 12 to get 4.
\left(-2v^{2}\right)x=4
The equation is in standard form.
\frac{\left(-2v^{2}\right)x}{-2v^{2}}=\frac{4}{-2v^{2}}
Divide both sides by -2v^{2}.
x=\frac{4}{-2v^{2}}
Dividing by -2v^{2} undoes the multiplication by -2v^{2}.
x=-\frac{2}{v^{2}}
Divide 4 by -2v^{2}.
