Answer :
A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.
Step-by-step explanation :
We start by dividing the inequality by 3 to get
8 -4x < 2(x-5)
And we can divide by 2 to simplify further to
4 -2x < x-5
Now, we add 2x+5, which gives
9 < 3x
and then divide by 3 again:
3 < x
