Answer

The inequality has no solution.

Work Step by Step

The given inequality is $\Rightarrow -3(3y-2)\lt 1-9y$ Use distributive property. $\Rightarrow -9y+6\lt 1-9y$ Subtract $1$ from each side. $\Rightarrow -9y+6-1\lt 1-9y-1$ Simplify. $\Rightarrow -9y+5\lt -9y$ Add $9y$ to each side. $\Rightarrow -9y+5+9y\lt -9y+9y$ Simplify. $\Rightarrow 5\lt 0$ False. Hence, the inequality has no solution.
