Answer:
Step-by-step explanation: Since you know the equation the first step is to set it equal to 0, so 1/2x+-3=0, from here you just solve using algebra, with the goal of getting x by itself. There are three good options with one that I would say is the best. You can multiply both sides of the equation by 2, subtract -3 from both sides or subtract 1/2x from both sides, if you don't understand that let me know. The best I would say is subtract -3 so both sides are positive. that leaves you with 1/2x=3. Can you tell what to do from here?
