A tricycle has 3 wheels. A bicycle has 2 wheels. 8 tricycles and bicycles have 22 wheels altogether. How many tricycles are there? How many bicycles are there?

b = bikes                           wheels = 2b

then 8-b - trikes                wheels = 3 ( 8-b)      summed = 22

 

 

2b         +     3(8-b)       = 22        solve for b    then t = 8-b
