Answer 1

George And Carmen Went On A Bicycle Trip. They Took A Bus To Their Starting Point Then Biked The Rest. 
They Traveled 275 Kilometers In Total, 
And They Biked 55 Kilometers More Than They Were Bussed. 
Let X=Kilometers Traveled By Bike 
Let Y=Kilometers Traveled By Bus. 
Find How Many Kilometers They Traveled By Bike.
--------
X + Y = 275 km
X = Y + 55
-------------

Substitute or X and solve for "Y":
Y+55 + Y = 275
2Y = 220
Y = 110 km (distance traveled by Bus)
-------
Solve for "X":
X = Y + 55
X = 110+55 = 165 km (distance traveled by Bike)
