2x-5=9
Square both sides of the equation.
2x-5-\left(-5\right)=9-\left(-5\right)
Add 5 to both sides of the equation.
2x=9-\left(-5\right)
Subtracting -5 from itself leaves 0.
2x=14
Subtract -5 from 9.
\frac{2x}{2}=\frac{14}{2}
Divide both sides by 2.
x=\frac{14}{2}
Dividing by 2 undoes the multiplication by 2.
x=7
Divide 14 by 2.
