Suppose that you are traveling straight from los angeles, california to denver, colorado, stopping overnight in page, arizona. the distance from l. a. to denver is 1,017 miles, and the road connecting the three cities is a straight line. if the distance from l. a. to page is 205 miles greater than the distance from page to denver, how far is l. a. from page, and how far is page from denver?

The answer is
LA to Page: 611 mi
Page to Denver: 406 mi

Total distance from LA to Denver is T.
The distance LA to Page is x
The distance Page to Denver is y.

T = x + y
T = 1017

x + y = 1017

The distance from L.A. to Page (x) is 205 miles greater than the distance from Page to Denver (y):
x = y + 205

The system of two equations:
x + y = 1017
x = y + 205

Substitute x from the second equation into the first one:
y + 205 + y = 1017
2y + 205 = 1017
2y = 1017 - 205
2y = 812
y = 812 / 2
y = 406 mi (Page to Denver)

x = y + 205 = 406 + 205 = 611 mi (LA to Page)

Could you make it more clear?
