First set up the equation based on the description.
\(\frac{1}{3}\) x + 16 = 3x
Use subtraction to get the "x"s on one side of the equation. You can next subtract \(\frac{1}{3}\) x from both sides.
16 = \(\frac{8}{3}\) x
Now you can multiply both sides of the equation by \(\frac{3}{8}\) to solve for x
x = 6
