Solve for x
x=-\left(2-y\right)^{2}+3
-\left(2-y\right)\geq 0
Solve for x (complex solution)
x=-\left(2-y\right)^{2}+3
y=2\text{ or }arg(2-y)\geq \pi
Solve for y
y=\sqrt{3-x}+2
x\leq 3

\sqrt{3-x}+2=y
Swap sides so that all variable terms are on the left hand side.
\sqrt{3-x}=y-2
Subtract 2 from both sides.
-x+3=\left(y-2\right)^{2}
Square both sides of the equation.
-x+3-3=\left(y-2\right)^{2}-3
Subtract 3 from both sides of the equation.
-x=\left(y-2\right)^{2}-3
Subtracting 3 from itself leaves 0.
\frac{-x}{-1}=\frac{\left(y-2\right)^{2}-3}{-1}
Divide both sides by -1.
x=\frac{\left(y-2\right)^{2}-3}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-\left(y-2\right)^{2}+3
Divide \left(y-2\right)^{2}-3 by -1.
