Can someone explain how to do

Alinara [238K]

The solution is:

$3\leq y\leq 10$

y ≥ 3 and y≤10

Further explanation:

The given inequality is compound inequality which is solved in two parts.

Given inequality is:

$10 \leq 2y+4\leq 24$

The two inequalities which will be formed are:

$2y+4\geq 10\\2y+4\leq 24$

Solving one by one

$2y+4\geq 10\\2y+4-4\geq 10-4\\2y\geq 6\\\frac{2y}{2} \geq \frac{6}{2} \\ y \geq 3\\2y+4\leq 24\\2y+4-4\leq 24-4\\2y\leq 20\\\frac{2y}{2}\leq \frac{20}{2} \\y\leq 10$

The solution is:

$3\leq y\leq 10$

y ≥ 3 and y≤10
