We'll do the first one. I can't read the variable, but it looks like a [tex]\theta[/tex] so that's what I'll use, but it doesn't matter.
First, get the variable by itself:
[tex]\theta<6[/tex]
You get that before you multiply each side by two.
Now, you color the line so that all values that are less than 6 are shaded, so you put an open circle at 6 since it's not included and then you shade everything to the left.
