Subtract $2$ from each section of the inequality because it does not contain the variable we are trying to solve for.

$5 - 2 \leq y \leq 11 - 2$

Step 2

Subtract $2$ from $5$ .

$3 \leq y \leq 11 - 2$

Step 3

Subtract $2$ from $11$ .

$3 \leq y \leq 9$

Step 4

The result can be shown in multiple forms.
