Answer

$(-\infty,1)$

Work Step by Step

$\frac{x}{6}+\frac{3x-2}{2}\lt\frac{2}{3}$ Multiply both sides by 6, the least common multiple, so eliminate fractions. $6(\frac{x}{6})+6(\frac{3x-2}{2})\lt6(\frac{2}{3})$ $x+3(3x-2)\lt\frac{12}{3}$ $x+9x-6\lt4$ Combine like terms. $10x-6\lt4$ Add 6 to both sides. $10x-6+6\lt4+6$ $10x\lt10$ Divide both sides by 10. $10x\div10\lt10\div10$ $x\lt1$ This is written in interval notation as $(-\infty,1)$ where ) indicates that the solution set for x approaches 1 but does not include 1.
