\sqrt{x-8}+\sqrt{y-2}-\sqrt{y-2}=-\sqrt{y-2}
Subtract \sqrt{y-2} from both sides of the equation.
\sqrt{x-8}=-\sqrt{y-2}
Subtracting \sqrt{y-2} from itself leaves 0.
x-8=y-2
Square both sides of the equation.
x-8-\left(-8\right)=y-2-\left(-8\right)
Add 8 to both sides of the equation.
x=y-2-\left(-8\right)
Subtracting -8 from itself leaves 0.
x=y+6
Subtract -8 from y-2.
\sqrt{y-2}+\sqrt{x-8}-\sqrt{x-8}=-\sqrt{x-8}
Subtract \sqrt{x-8} from both sides of the equation.
\sqrt{y-2}=-\sqrt{x-8}
Subtracting \sqrt{x-8} from itself leaves 0.
y-2=x-8
Square both sides of the equation.
y-2-\left(-2\right)=x-8-\left(-2\right)
Add 2 to both sides of the equation.
y=x-8-\left(-2\right)
Subtracting -2 from itself leaves 0.
y=x-6
Subtract -2 from x-8.
