At a bicycle store, there were a bunch of bicycles and tricycles. if there were 32 seats and 69 wheels, how many bicycles and how many tricycles were there?

You have to find a divisible number by the subtracted amount of seats left

60wheels/29 seats doesn't equal a whole number

your most likely confused what im talking about so lets break it down a tricycle has three wheels one seat so three tricycles have 9 wheels 3 seats 69 - 9 = 60
32 - 3 = 29  60/29

but 48/24 = 2 so the do some critical thinking

24 bicycles 69 wheels 24 bicycles have 48 wheels 69 - 48 = 21
21/3 = 7

so now we know we have 24 bicycles and 7 tricycles
