Marcus does inventory of his bike shop by counting the number of seats and wheels. Currently, his store only holds bicycles (2 wheels) and tricycles (3 wheels). One day, Marcus counts 14 seats and 36 wheels. The equation representing the total number of seats is b + t = 14 where b is the number of bicycles and t is the number of tricycles.

Write an equation, in standard form (Ax + By = C), to represent the number of for the situation given.
