3x-5=4
Square both sides of the equation.
3x-5-\left(-5\right)=4-\left(-5\right)
Add 5 to both sides of the equation.
3x=4-\left(-5\right)
Subtracting -5 from itself leaves 0.
3x=9
Subtract -5 from 4.
\frac{3x}{3}=\frac{9}{3}
Divide both sides by 3.
x=\frac{9}{3}
Dividing by 3 undoes the multiplication by 3.
x=3
Divide 9 by 3.
