The teton club has hiked 18.5 miles
and has x miles left to go. the club
plans to hike 25 miles altogether.

25=18.5+x

x=6.5 miles

Step-by-step explanation:

isolate the x by subtracting 18.5 on both sides.

25-18.5=18.5-18.5+x

you will end up with 6.5 because 25-18.5 is 6.5

therefore, x=6.5 miles
