y=3x^{2}+8+2a
Use the distributive property to multiply 2 by 4+a.
3x^{2}+8+2a=y
Swap sides so that all variable terms are on the left hand side.
8+2a=y-3x^{2}
Subtract 3x^{2} from both sides.
2a=y-3x^{2}-8
Subtract 8 from both sides.
2a=-3x^{2}+y-8
The equation is in standard form.
\frac{2a}{2}=\frac{-3x^{2}+y-8}{2}
Divide both sides by 2.
a=\frac{-3x^{2}+y-8}{2}
Dividing by 2 undoes the multiplication by 2.
a=-\frac{3x^{2}}{2}+\frac{y}{2}-4
Divide y-3x^{2}-8 by 2.
