Solve by using a system of two equations in two variables.

Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! let x="Gretchen's paddling rate in still water", and let y=" rate of the current"
"Gretchen paddles a canoe upstream at 3mi/h" __ x-y=3
"Traveling downstream, she travels at 8mi/h" __ x+y=8
adding the equations will eliminate the y terms
solve for x, then substitute to find y
