$x = 15$ $color(green)(x=15)$

Explanation:

Given
$XXX \frac{1}{3} x - 4 = 1$ $color(white)("XXX")1/3x-4=1$

Multiply everything on both sides by $3$ $3$ to get rid of the fraction.
$XXX x - 12 = 3$ $color(white)("XXX")x-12=3$

Add $12$ $12$ to both sides to isolate the variable $x$ $x$ .
$XXX x = 15$ $color(white)("XXX")x=15$
