Question 1002489
Inequalities should be treated like problems with weird equal signs. 

x-6<-3

So we want to get x by itself before we can graph this to make it more simple.

Add 6 to both sides

x<3 awwwe cute a heart...

anyways
x < 3 

so on a number line you would put an open dot on the tick mark 3 and draw a line continuing on forever on the left side of the 3. Since x can equal all values less than 3
