SOLUTION
Let the number of people who live in the Lake Section = x
Let the number of people who live in the Hill Section = 295 + x ,
Total = 3496
The equation is x + ( 295 + x ) = 3496
x + x + 295 = 3496
2 x + 295 = 3496
2x = 3496 - 295
2 x = 3201
Divide both sides by 2 , we have :
x = 3201 / 2
x = 1600 .5
x = 1601 ( nearest whole number)
The number of people who live in the Lake Section = x = 1601
The number of people who live in the Hill Section = 295 + x = 295 + 1601 = 1896
