Answer: Option E
Step-by-step explanation: You want to subtract x from both sides and add one from both sides in order to get the variables on one side.
When you do this you get 3x is greater than or equal to 3. Now divide by three on both sides. This becomes x is greater than or equal to 1. You want to find the number line with a closed circle on 1 since to represent the "or equal to" and you want it to go in the direction of left to right to represent the increase since it is "greater than".
