3\sqrt{x-3}+1-1=7-1
Subtract 1 from both sides of the equation.
3\sqrt{x-3}=7-1
Subtracting 1 from itself leaves 0.
3\sqrt{x-3}=6
Subtract 1 from 7.
\frac{3\sqrt{x-3}}{3}=\frac{6}{3}
Divide both sides by 3.
\sqrt{x-3}=\frac{6}{3}
Dividing by 3 undoes the multiplication by 3.
\sqrt{x-3}=2
Divide 6 by 3.
x-3=4
Square both sides of the equation.
x-3-\left(-3\right)=4-\left(-3\right)
Add 3 to both sides of the equation.
x=4-\left(-3\right)
Subtracting -3 from itself leaves 0.
x=7
Subtract -3 from 4.
