Solve for x
x=\left(y+6\right)^{2}
y+6\geq 0
Solve for x (complex solution)
x=\left(y+6\right)^{2}
y=-6\text{ or }arg(y+6)<\pi
Solve for y
y=\sqrt{x}-6
x\geq 0

\sqrt{x}-6=y
Swap sides so that all variable terms are on the left hand side.
\sqrt{x}=y+6
Add 6 to both sides.
x=\left(y+6\right)^{2}
Square both sides of the equation.
