River c is 200 miles longer Than river D. if the sum of their lengths is 5,550 miles what is the length of each river?
The length of river c is __ miles , and the length of river D is __ miles. ?
~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

The condition says that

C + D = 5550,   (1)
C - D =  200.   (2)

Add these two equations (both sides). You will get

2C = 5550 + 200,

2C = 5750,

C =  = 2875 miles.

Having this, can you find D on your own?
