\frac{30}{6}=\sqrt{2m-5}
Divide both sides by 6.
5=\sqrt{2m-5}
Divide 30 by 6 to get 5.
\sqrt{2m-5}=5
Swap sides so that all variable terms are on the left hand side.
2m-5=25
Square both sides of the equation.
2m-5-\left(-5\right)=25-\left(-5\right)
Add 5 to both sides of the equation.
2m=25-\left(-5\right)
Subtracting -5 from itself leaves 0.
2m=30
Subtract -5 from 25.
\frac{2m}{2}=\frac{30}{2}
Divide both sides by 2.
m=\frac{30}{2}
Dividing by 2 undoes the multiplication by 2.
m=15
Divide 30 by 2.
