Select the graph of the solution. Click on the graph until the correct one appears.

$x2$

So, Graph of Image 1 is correct.

Step-by-step explanation:

We need to find the graph of the solution o the equation $|x|+3>5$

Solving:

$|x|+3>5$

Adding -3 on both sides

$|x|+3-3>5-3$

$|x|>2$

Applying absolute rule: if |u|>a then u>a or u<-a

$x2$

So, all values greater than 2 and less than -2 are included.

So, Graph of Image 1 is correct.
