The solution to the system of inequalities given is: $\frac{4}{3} \leq y \leq 4$

<h3>What is the solutions to a system of inequalities?</h3>

The solution is the set of values that respect all conditions of the system.

The first condition is:

$3y - 13 \geq -9$

$3y \geq 4$

$y \geq \frac{4}{3}$

The second condition is:

$3y - 13 \leq -1$

$3y \leq 12$

$y \leq \frac{12}{3}$

$y \leq 4$

The intersection of the conditions, which is the solution to the inequality, is:

$\frac{4}{3} \leq y \leq 4$
