<em>Greetings from Brasil...</em>

Let's solve this inequality.

Let's isolate X. For this, the elements that are with it must be sent to both sides:

- 3 < - 4X + 1 < 13

- 3 - 1 < - 4X < 13 - 1

- 4 < - 4X < 12

Answer:

$\dfrac{-x}{3}$ should be added to the given equation.

Step-by-step explanation:

Let a is added to the given equation.

According to the given condition,

$\dfrac{5x}{6}-4+a=\dfrac{x}{2}-4\\\\a=\dfrac{x}{2}-4+4-\dfrac{5x}{6}\\\\a=\dfrac{x}{2}-\dfrac{5x}{6}\\\\a=\dfrac{3x-5x}{6}\\\\a=\dfrac{-2x}{6}\\\\a=\dfrac{-x}{3}$

So, $\dfrac{-x}{3}$ should be added to the given equation.
