Answer 1

Answer:

y=1 for $y\leq 1$

Step-by-step explanation:

We can solve an inequality much like we solve an equation. We will use inverse operations to isolate y. If we need to divide by a negative then we will need to flip the inequality.

$2y+9\leq 11\\2y+9-9\leq 11-9\\2y\leq 2\\\frac{2y}{2}\leq \frac{2}{2} \\y\leq 1$

First, we moved 9 across the equal sign to combine it with 11 by subtracting by 9 from both sides.

Second, we divided both sides by 2.

$y\leq 1$ is the solution. All solutions equal to 1 and less than 1 will work.
