$x = -\frac{4}{3}$ or $x = \frac{4}{3}$

Work Step by Step

First, we subtract $1$ from each side of the equation: $2|3x| = 8$ Divide each side by $2$: $|3x| = 4$ Divide each side by $3$: $|x| = \frac{4}{3}$ Take the absolute value of both sides of the equation: $x = -\frac{4}{3}$ or $x = \frac{4}{3}$
