Levinsonâ€™s Hardware has a number of bikes and tricycles for sale. There are 27 seats and 60 wheels all told. Determine how many bikes and tricycles there are in the store

If there were 27 bikes, then there are 6 wheels left over. So there must be 6 tricycles and 276=21 bicycles.

what do you mean there are 6 wheels left over?

If there were only 27 bikes,
2*27=54
then there will be 6 wheels left.
Change each extra wheel together with a bike for a tricycle, you will get 6 tricycles and 21 bikes.
