\sqrt{4x-7}-3-\left(-3\right)=-\left(-3\right)
Add 3 to both sides of the equation.
\sqrt{4x-7}=-\left(-3\right)
Subtracting -3 from itself leaves 0.
\sqrt{4x-7}=3
Subtract -3 from 0.
4x-7=9
Square both sides of the equation.
4x-7-\left(-7\right)=9-\left(-7\right)
Add 7 to both sides of the equation.
4x=9-\left(-7\right)
Subtracting -7 from itself leaves 0.
4x=16
Subtract -7 from 9.
\frac{4x}{4}=\frac{16}{4}
Divide both sides by 4.
x=\frac{16}{4}
Dividing by 4 undoes the multiplication by 4.
x=4
Divide 16 by 4.
