Solve for y
y=\frac{15+3x-x^{2}}{2}
Solve for x (complex solution)
x=\frac{\sqrt{69-8y}+3}{2}
x=\frac{-\sqrt{69-8y}+3}{2}
Solve for x
x=\frac{\sqrt{69-8y}+3}{2}
x=\frac{-\sqrt{69-8y}+3}{2}\text{, }y\leq \frac{69}{8}

-3x+2y=15-x^{2}
Subtract x^{2} from both sides.
2y=15-x^{2}+3x
Add 3x to both sides.
2y=15+3x-x^{2}
The equation is in standard form.
\frac{2y}{2}=\frac{15+3x-x^{2}}{2}
Divide both sides by 2.
y=\frac{15+3x-x^{2}}{2}
Dividing by 2 undoes the multiplication by 2.
