Answer

$\{0,\frac{4}{3}\}$

Work Step by Step

Use the square root method by taking the square root of both sides. $\sqrt{(3x-2)^2}=\pm\sqrt {4}$ $3x-2=\pm\sqrt {2^2}$ $3x-2=\pm2$ Split the expression to obtain: $3x-2 =2\quad $ or $\quad 2y+3=-2$ Add $2$ to both sides of both equations. $3x-2 +2=2+2$ or $3x-2+2=-2+2$ Simplify. $3x=4\quad $ or $\quad 3x=0$ Divide both sides by $3$. $x=\frac{4}{3}$ or $x=0$ Hence, the solution set is $\{0,\frac{4}{3}\}$.
