2\sqrt{x+3}-4=y
Swap sides so that all variable terms are on the left hand side.
2\sqrt{x+3}=y+4
Add 4 to both sides.
\frac{2\sqrt{x+3}}{2}=\frac{y+4}{2}
Divide both sides by 2.
\sqrt{x+3}=\frac{y+4}{2}
Dividing by 2 undoes the multiplication by 2.
\sqrt{x+3}=\frac{y}{2}+2
Divide y+4 by 2.
x+3=\frac{\left(y+4\right)^{2}}{4}
Square both sides of the equation.
x+3-3=\frac{\left(y+4\right)^{2}}{4}-3
Subtract 3 from both sides of the equation.
x=\frac{\left(y+4\right)^{2}}{4}-3
Subtracting 3 from itself leaves 0.
