Question 1126923
x are  conservatives at the beginning,so there were 0.6x at the end
260-x were liberals at the beginning, so there were 0.7(260-x) at the end
conservatives at the end were 0.6x+(.3)(260-x)=260-x
Or 0.6x+78-.3x=260-x
1.3x=182
x=140 conservatives at the beginning and they dropped by 56 to 84.  They gained 36 to end at 120.
260-x=120 liberals at the beginning, and they gained 56 and lost 36 to end at 140
