-v=8+x
Swap sides so that all variable terms are on the left hand side.
-v=x+8
The equation is in standard form.
\frac{-v}{-1}=\frac{x+8}{-1}
Divide both sides by -1.
v=\frac{x+8}{-1}
Dividing by -1 undoes the multiplication by -1.
v=-\left(x+8\right)
Divide 8+x by -1.
x=-v-8
Subtract 8 from both sides.
