Northern Maywood voted 60% to 40% in favor of a water project. Southern Maywood voted 90% to 10% against the prject. The project passed 55% to 45%. If 5900 people voted, how many were from Southern Maywood.
Let X be the number of votes cast in S.Maywood. Then 5900-X were cast in N. Maywood. The total number of yes votes was 0.55*5900 = 3245
0.1X + 0.6(5900-X) = 3245
-0.5X = 3245 - 3540 = -295
One more step and you are there.
