number of bikes --- b
number of trikes--- t
(assume: a bike has 2 pedals and 2 wheels, a trike has 2 pedals and three wheels)
2b+2t = 80 --- > b = 40-t
2b + 3t = 98
2(40-t) + 3t = 98
80-2t+3t=98
t=18
b = 22
He has 22 bikes and 18 trikes
In a shop selling bicycle and tricycle, a total of 80 pedals and a total of 98 wheels were counted. How many bicycles and tricycles does he have?
