\sqrt{x}-\sqrt{y}=43-12\sqrt{7}
Swap sides so that all variable terms are on the left hand side.
\sqrt{x}=43-12\sqrt{7}+\sqrt{y}
Add \sqrt{y} to both sides.
x=\left(\sqrt{y}+43-12\sqrt{7}\right)^{2}
Square both sides of the equation.
\sqrt{x}-\sqrt{y}=43-12\sqrt{7}
Swap sides so that all variable terms are on the left hand side.
-\sqrt{y}=43-12\sqrt{7}-\sqrt{x}
Subtract \sqrt{x} from both sides.
\frac{-\sqrt{y}}{-1}=\frac{-\sqrt{x}+43-12\sqrt{7}}{-1}
Divide both sides by -1.
\sqrt{y}=\frac{-\sqrt{x}+43-12\sqrt{7}}{-1}
Dividing by -1 undoes the multiplication by -1.
\sqrt{y}=\sqrt{x}+12\sqrt{7}-43
Divide 43-12\sqrt{7}-\sqrt{x} by -1.
y=\left(\sqrt{x}+12\sqrt{7}-43\right)^{2}
Square both sides of the equation.
