3x=x_{3}+24
The equation is in standard form.
\frac{3x}{3}=\frac{x_{3}+24}{3}
Divide both sides by 3.
x=\frac{x_{3}+24}{3}
Dividing by 3 undoes the multiplication by 3.
x=\frac{x_{3}}{3}+8
Divide 24+x_{3} by 3.
24+x_{3}=3x
Swap sides so that all variable terms are on the left hand side.
x_{3}=3x-24
Subtract 24 from both sides.
