The circle is shaded which indicates that the inequality is equal to. The circle is on -3 and extends towards numbers that are greater than -3. Thus, all numbers are can be equal to or greater than -3.
Since opposite angles are the same, we can set the equations together. 5x+12=6x-10. We then subtract 5x from both sides to get 12=x-10. Then add 10 to both sides to get x=22.
