4\sqrt{x}+7-7=23-7
Subtract 7 from both sides of the equation.
4\sqrt{x}=23-7
Subtracting 7 from itself leaves 0.
4\sqrt{x}=16
Subtract 7 from 23.
\frac{4\sqrt{x}}{4}=\frac{16}{4}
Divide both sides by 4.
\sqrt{x}=\frac{16}{4}
Dividing by 4 undoes the multiplication by 4.
\sqrt{x}=4
Divide 16 by 4.
x=16
Square both sides of the equation.
