Number of times she climbed 5-mile mountain trail = x
Number of times she climbed 10-mile trail = y
total distance of the 5-mile mountain trail will be = 5*x =5x
total distance of the 10-mile mountain trail will be = 10*y = 10y
equation that can be used to find the number of times she hiked each trail is therefore
5x + 10y = 90
