If you want my honest opinion i believe that 2 & 4 are the correct answers.
Answer: one good way they could avoided it's downfall was a better ruler
First subtract the 2 to isolate the 7x. Remember what you do to one side you do to the other, so then you would subtract 2 from 30 as well giving you 7x=28. After that in order to isolate x, you would divide by 7 on both sides giving you x=4.
The answer would be white resistance to desegregation.
