x-3=3\sqrt{7} x-3=-3\sqrt{7}
Take the square root of both sides of the equation.
x-3-\left(-3\right)=3\sqrt{7}-\left(-3\right) x-3-\left(-3\right)=-3\sqrt{7}-\left(-3\right)
Add 3 to both sides of the equation.
x=3\sqrt{7}-\left(-3\right) x=-3\sqrt{7}-\left(-3\right)
Subtracting -3 from itself leaves 0.
x=3\sqrt{7}+3
Subtract -3 from 3\sqrt{7}.
x=3-3\sqrt{7}
Subtract -3 from -3\sqrt{7}.
x=3\sqrt{7}+3 x=3-3\sqrt{7}
The equation is now solved.
