You can put this solution on YOUR website! in last saturday's parade, tom counted a total of 76 bicycles and tricycles, for a total of 227 wheels. how many tricycles were in the parade?
---------------------------
Quantity Equation: b + t = 76
Wheel Equations: 2b + 3t = 227
-------------------------------------
Multiply thru the Quantity Equation by 2 to set it up for elimination:
2b + 2t = 152
---
Subtract that from the Wheel Equation:
t = 75 (# of tricycles)
-------------
Substitute into b + t = 76 to solve for "b":
b = 1 (# of bicycles)
