Answer

No solution. The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow -2|y-3|-5 \geq -4$ Add $5$ to each side. $\Rightarrow -2|y-3|-5+5 \geq -4+5$ Simplify. $\Rightarrow -2|y-3| \geq 1$ Divide each side by $-2$. Reverse the inequality symbol. $\Rightarrow \frac{-2|y-3|}{-2} \leq \frac{1}{-2}$ Simplify. $\Rightarrow |y-3| \leq -\frac{1}{2}$ The absolute value of an expression must be greater than or equal to zero. The expression $|y-3|$ cannot be less than zero. Hence, the inequality has no solution.
