Question 17094: West High School's population is 250 less than twice the population of East High School. Combinded, the serve 2858 students. how many students attend the West High School? Answer by rapaljer(4671) (Show Source):
Looks like two equations and two unknowns:
W= 2E - 250
W + E = 2858
Substitute the W from the first equation into the second equation:
W + E = 2858
(____) + E = 2858
(2E -250) + E = 2858
3E - 250 = 2858
3E -250+250 = 2858 + 250
3E = 3108
E = 1036 = Population of East High
W= 2E -250 = 2(1036) -250 = 1822 = Population of West High
