Question 1095293: In the United States, the number of nuclear power plants in the south exceeds that in the midwest by 11. together these two areas have a total of 73 nuclear power plants. How many are located in the South? Answer by ikleyn(52786) (Show Source):
S - M = 11,
S + M = 73.
------------------Add the two equations. You will get
2S = 11 + 73 = 84, which implies S = = 42 power plants in the South.
Then in Midwest there are M = 73 - S = 73 - 42 = 31 power plants.
