Please help! It’s due tomorrow it also says to show my work

Given:
The inequality is
[tex]x+19\leq 23[/tex]
To find:
The value of x and then graph on the number line.
Solution:
We have,
[tex]x+19\leq 23[/tex]
Subtracting 19 from both sides, we get
[tex]x+19-19\leq 23-19[/tex]
[tex]x\leq 4[/tex]
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
